Re: [MORPHMET] new paper: elephant seal nose-metrics

2019-03-19 Thread Mauro Cavalcanti
Dear Andrea,

Absolutely fascinating!

Well, although not using GM methods, the book by William B. Evans & Alexey
V. Yablokov, "Noninvasive Study of Mammalian Populations" (Sofia/Moscow:
Pensoft, 2004) provides a lot of interesting ideas and insights on the use
of analytical techniques for living, non-sedated animals in the field. GM
methods would offer a powerful contribution in this regard.

With warmest regards,

Re: [MORPHMET] Phylogenetic tree in MorphoJ-regrading

2019-01-28 Thread Mauro Cavalcanti
Arvind,

The NEXUS format is used to represent phylogenetic trees, on which MorphoJ
will map your shapes. You don't prepare 2D data in NEXUS format, as the
software does not compute phylogenetic trees itself,  See the MorphoJ
documentation (
http://www.flywings.org.uk/MorphoJ_guide/frameset.htm?index.htm),
specifically the item "Comparison Menu" -> "Map Onto Phylogeny" for details.

By the way, a comprehensive description of the NEXUS format can be found in
the fine paper by Madison et al (1997):

David R. Maddison, David L. Swofford, Wayne P. Maddison. " NEXUS: An
Extensible File Format for Systematic Information".  Systematic Biology,
Vol. 46, No. 4 (Dec., 1997), pp. 590-621.

Hope this helps.

Re: [MORPHMET] Copy of TPS files with 'include path'

2017-05-14 Thread Mauro Cavalcanti
Gabriel,

TPS files are regular text files with data structured in a certain way.

Just open your TPS file in a plain text editor (Notepad++ is a good choice)
and fix the paths manually using the regular search-and-replace facility.

Hope this helps.

Re: [MORPHMET] Measurements to Landmarks

2016-11-09 Thread Mauro Cavalcanti
Dear Edgar,

Back in the 1990's, I have used this procedure to convert several datasets
of  measurements into landmark coordinates. I used a program which
implemented the method devised by Carpenter et al. written in Basic for
MS-DOS (a long gone programming language for a long gone operating system).
The algorithm has been subsequently implemented by Dennis Slice in earlier
versions of the Morpheus software.

The method works quite well and I have published a few studies using it. If
you are interested, I can provide you with a copy of the program I used,
although using an earlier version of Morpheus would perhaps be a better
idea as this software runs on more recent machines.

Salud!

Re: [MORPHMET] model II regression statistics PAST

Patrick,

PAST is "free" as in "free beer", not as in *free speech*. It is gratis,
but not open. The problem you have is just typical of such black box
approach to scientific software development -- since one cannot see the
source code, it is not possible to check how this or that algorithm is
implemented.

Stick to R, where nothing is hidden.

[MORPHMET] Complaints about 'geomorph' R package

2015-12-16 Thread Mauro Cavalcanti
Dear members of the R geomorph Development Team,

As you surely know, I am a big fan of the 'geomorph' R package, which I
have been using since its inception (as part of a larger personal move to
do every possible analysis, morphometric or not, using R). Several times, I
have provided tentative bug reports and humble suggestions for improvements
(that sometimes have been incorporated into new releases of the package).

But with due respect, today I have a few severe complaints, that I am
posting here because they may have been of concern for other
morphometricians working with the geomorph package.

My first -- and biggest -- complaint concern the way landmark coordinates
captured by the 'digitize2d' routine are  stored in the latest version of
geomorph. There seems to have been some change in the code (undocumented as
far as I could see) which altered the scaling of the coordinates -- as a
result, I lost weeks of work on a file with more than 70 fish specimens
because when I opened the file in geomorph 2.17 to re-start digitizing the
remaining specimens (after having digitized about 50 in geomorph 2.15), all
coordinates were unexpectedly changed and the file became even unreadable
by Jim Rohlf's tps programs (but before this change in geomorph I could
have the tps programs read files digitized in geomorph without trouble).

Well, at first I solved this by simply downgrading my version of geomorph,
returning to the old 2.15 version and everything worked fine. Since I use
RStudio, i just had to remember to unckeck geomorph in the list of packages
to be updated.

But today, to my dismay and further annoyance, when I upgraded several
packages in my R installation -- even unckecking as usual the geomorphy
entry -- I got a strange error message which turned geomorph (whatever the
installed version) useless! Here it is:

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()),
versionCheck = vI[[j]]) :
  there is no package called 'Biostrings'
ERROR: lazy loading failed for package 'geomorph'
* removing 'C:/Program Files/R/R-3.1.3/library/geomorph'


The geomorph package depends on other two packages, 'ape' and 'rgl', but
none of them have been upgraded recently and both load fine and without any
error messages, therefore I suppose the above error is generated by
geomorph itself.

Right, the error message about a missing package may be a minor (and easily
fixed) issue. But so is not the changes done to the digitize2d function,
which lead to data loss and waste of time and resources! Even if there are
some good reason (as surely does!) for changing the scaling of landmark
coordinates, such change should no tbe done without at least providing
users with the option of using the previous mode of operation of the
routine. Besides, such change should be carefully documented (and I could
not fund any mention to it in the "NEWS" file of the latest versions of
geomorph).

I hope you understand my reasons for complaining, and I look forward to
obtaining directions on how to get out of this mess (currently, I cannot
even use geomorph, whatever the version, because as a a result of the
"misisng package" error, the entire package was automatically wiped out of
my R installation...)

Life is short (so we need R)!

[MORPHMET] Yet another sequel to complaints about 'geomorph' R package

2015-12-16 Thread Mauro Cavalcanti
Dear members of the geomorph R package Development Team,

I at least have been able to track down the "missing library" error when
attempting to install even previous versions of geopmorph.

It turns out that geomorph depends upon a package called 'phangorn' --
which has just been updated to make use of "Biostrings". At least one other
R package (phytools) is also dependent upon phangorn Iand therefore upon
Biostrings too).

The fact that the Biostrings package has not been installed as a depedency
of the latest phangorn is due to the fact that the Bioconductor Project
(and associated packages) is not on CRAN. A big mess, indeed...

Hope this helps!

It seems that these complaints about geomorph are turning to become a
series with many sequels as "Star Wars"...

May the Force Be With You! ;-)

[MORPHMET] A sequel to complaints about 'geomorph' R package

2015-12-16 Thread Mauro Cavalcanti
Dear members of the geomorph R package Development Team,

After posting my complaints about the current problems in the geomorph R
package I have just stumbled upon, I have been able to at least find a
workaround to the annoying message about the missing "Biostrings" package.

I found out that "Biostrings" is part of the huge "Bioconductor" project
which aims to develop a large set of tools for bioinformatics. Following
the directions here (
https://bioconductor.org/packages/release/bioc/html/Biostrings.html) I have
been able to install the required library (plus several other packages of
ehich Biostrings depends) and afterwards could re-install version 2.15 of
geomorph. Now everything works as before!

But this is a makeshift solution. I have no idea why even previous versions
of geomorph are now requiring "Biostrings" (which are part of Bioconductor,
that I have never had in my R installation). Furthermore, the problem with
the scaling of landmark coordinates in the current version of geomorph
still stands and should be properly treated by offering an option to keep
the 'old' mode in the digitize2d function.

Hope this helps.

Re: [MORPHMET] Question about tpsSmall

Zakia,

The small in tpsSmall does not refer to sample size, but to the amount of
variation in shape in a data set, in order to check if said variation is
small enough to allow performing statistical analyses of the data in the
linear tangent approximation of Kendall's shape space. I find tpsSmall
plots very helpful to check my data before performing more sophisticated
analyses (like relative warps).

Hope this helps.

Re: [MORPHMET] A question about PCA in geomorph

2015-04-12 Thread Mauro Cavalcanti
Dear Emma  ALL,

Indeed, when reading my data with readland.nts I get the data in the format
required by the geomorph analytical routines. The problem is that I was
calling by mistake a routine from Ian Dryden's shapes package (procGPA) to
generate the Procrustes-aligned coordinates, instead of the gpagen routine.
Fixed this and now everything works fine.

I take this opportunity to ask another question, this time relating to the
plots generated by geomorph. Is there a way to customize them, including
for example axis labels in the PCA plots? In fact, the Quick Guide shows
these plots with labels, but I could not figure out how to include them in
my plots. Calling the R par function (as one should have done when using
the usual plot command) did not work.

Again, thanks for your help.

 If you read in your NTS data file using readland.nts, it will
 automatically be in the 3D array format required by plotTangentSpace (after
 you use gpagen to do a Procrustes Superimposition).

 If you have your data as a 2D matrix, you simply use arrayspecs to make it
 a 3D array.

Michael,

Thanks for your helpful message. Indeed, after posting my question about
plot customization, I was able to generate a PCA plot from plotTangentSpace
with axes labels, using the par function immediately before calling the
plotTangentSpace routine, as follows: par(xlab=PC 1, ylab=PC 2).
Obviously, the solution you suggested is even more generic and flexible and
it also works fine.

When means are available to customize the display of deformation grids,
then geomorph will be near perfection!

Thanks again for your help.

With best regards,

2015-04-12 11:19 GMT-03:00 Collyer, Michael michael.coll...@wku.edu:

  Mauro,

  The extractable parts from prcomp() are also extractable from
 plotTangentSpace.  One can make custom plots, relabel axes, change symbols,
 etc.  Example:

  myplot = plotTangentSpace(mydata)
 attributes(myplot) # shows extractable parts

  PC.scores = myplot$x

  par(…)
 plot(PC.scores, …)

  Keep in mind with plotTangentSpace, the product is actually multiple
 plots, as the transformation grids are also plots.  Therefore, it is not
 easy to pass on par() input to the result.  But because users can extract
 the scores, all base R plotting functions are available.

[MORPHMET] New version of The Morphometrics Library website

2014-09-30 Thread Mauro Cavalcanti
Dear ALL,

Just as Microsoft announced the shift from Windows 8.1 to Windows 10 (a
giant leap for mankind, no doubt!), I am pleased to announce that a new and
improved version of The Morphometrics Library (MorphoLib) website is now
available from http://morpholib.eu.pn/

All materials from the former version are of course available, but now much
better organized and accessible in a PHP-based content management system
which will make mantainence much easier and faster than the previous
version using simple plain HTML pages.

A new Software section has been added, listing just a few of the more
comprehensive program packages for geometric morphometrics analysis (plus
the available R libraries, as I think that is the way to go).

Also, a new reference list, on amphibians and reptiles (herptiles)
morphometrics has just been started; but notice that this is still quite
rudimentary and I have plenty of references on the subject (having an
interest in these critters myself), which I will add as time allows. This
list is also more eclectic in that it includes papers dealing with more
traditional morphometrics too. Many thanks to Dany Adams for providing the
initial stimulus for me to starting this yet another reference list.

Other lists have been updated, especially the list of references on
arthropods mantained by Ivan Huber with the inclusion of a lot of citations
sent to us by Hugo Benítez. Thanks a lot to Ivan and Hugo for their great
help!

Well, it looks like what started as a simple way to share my reference
lists on morphometrics has evolved by itself into an information portal
(well, sort of ;-))  on geometric morphometrics literature.

Hope it is useful.

 I cannot be certain about access to non-owners - I am, of course, the owner
 and it works perfectly for me. I think, but am not certain, that it should
 now be accessible to all as before: http://www.morphometrics.org.

[MORPHMET] MorphoLib access problems

2014-09-04 Thread Mauro Cavalcanti
Dear ALL,

A few visitors have reported that they have not been able to access the
MorphoLib website at http://morpholib.eu.pn, even suggesting that the URL
may not be valid. In fact, it is. What seems to happen is that some people
maybe behind a firewell that prevents access to websites with 'unusual'
domain names like '.pn' (which refers to the Pitcairn Islands!). In such
cases, I can only suggest trying access the site from a different location
(and a different ISP) and see if the problem persists.

MorphoLib is maintained entirely on the basis of my volunteer work, as a
service to the morphometrics community that for so many years has been so
helpful and resourceful to me. This means that I do not have any available
funds to maintain a domain and therefore resort to a free (but really very
reliable) hosting service which also offers me a free domain name (in this
case, morpholib (dot) eu (dot) pn.

In a world where violence (both against people and the natural environment)
seems to prevail, it is my deepest conviction that we, scientists, should
be strongly commited to openness and the free (both as free speech and,
when possible, also as 'free beer') sharing of information (which includes
ideas, data, and tools to process and and share them).

With warmest regards, :-)

[MORPHMET] MorphoLib updates

2014-09-03 Thread Mauro Cavalcanti
Dear ALL,

This is to announce the availability of updates to the Morphometrics
Library at http://morpholib.eu.pn

A new section on Links has been added, with a (non-exaustive!) list of
websites on morphometrics.

An entirely new list of bibliographic references, on plant geometric
morphometrics, has been added.

The list of references on mollusk morphometrics has been updated.

Thanks to Simon Mayo, Emma Sherrard, Ingo Schindler, and Corrado Costa for
sending me references. Thanks also to the Morpmetrics.org The Management
(;-)) for the excellent job in setting up the new, much improved,
Morphomet-L discussion list and overall inspiration

More soon...

Cheers,
