Re: [aroma.affymetrix] Re: CRMAv2 and Mapping250K_Nsp arrays
Hi Hernik, Clearing the cache as you suggested did the trick: clearCache(dirs=aroma.affymetrix, recursive=TRUE, prompt=FALSE) Calculation of the sets of pobes with common SNP nucleotide pairs took much more time after clearing the cache and I finally got 6 groups + missing as expected. There must have been some corrupt files in my cache. Thanks again for your help!

[aroma.affymetrix] Re: GenomeWideSNP_6 hg19
Hi Hendrik. Sure - I would like to share my annotation files. I made a new .ugp file without problems. Unfortunately, a known issue arises when creating the new .ufl file. When importing the ufl information from the NetAffx annotation files na31, the following warning appears: Warning messages: 1: In updateDataColumn.AromaTabularBinaryFile(this, .con = con, .hdr = hdr, : 4 values to be assigned were out of range [-32768,32767] and therefore censored to fit the range. Of these, 4 values in [42148,51916] were too large. 2: In updateDataColumn.AromaTabularBinaryFile(this, .con = con, .hdr = hdr, : 90 values to be assigned were out of range [-32768,32767] and therefore censored to fit the range. Of these, 90 values in [33603,21059245] were too large. Actually, some frangments are really very large (and other are very small): summary(ufl) length length.02 Min. :7 Min. :7 1st Qu.: 432 1st Qu.: 755 Median : 679 Median : 1433 Mean : 923 Mean : 1922 3rd Qu.: 976 3rd Qu.: 2609 Max. :32767 Max. :32767 NA's :29333 NA's :15585 This is different from annotation version na30. (The same issue came up with the Mouse Diversity Array. I wrote that in another thread.) Instead of modifying the annotation files and setting fragment length 2000 to NA etc., I would prefer to keep the original annotation and add a parameter to the function for fragment length normalization (max and min fragment length). What do you think? Also, I will write to the affymetrix forum and ask why they changed their annotation.

Correct, since the sequences on the actually chip never changes, the Aroma Cell Sequence (ACS) file is not changing either.

[aroma.affymetrix] Re: MOUSEDIVm520650 and CRMAv2
Hi Hendrik,
it works now without error messages! Thanks!
The chromosome explorer looks fine except for chromosomes 19. There
are links for chromosomes 20,21,22 and X in the navigation bar that do
not work (since mice do not have chr. 20,21,22). Y and M are not
linked. I read in this forum that the links currently are hard
coded. However, this is not a big problem for me.
Thanks,
Hans-Ulrich

Hi,
it looks like the patch wasn't applied. I've actually committed the
bug fix to CRAN where aroma.core v1.8.1 is now available. If you do
source(http://aroma-project.org/hbLite.R;);
hbInstall(aroma.affymetrix);
that one should install (and any patches will be dropped).
Let me know if you still have problems

Hi all,
I am using the Affymetrix MOUSEDIVm520650 chip. During the the
normalization step for fragment length, the aroma software complains
that no probes for enzyme 1 only exist (the same for enzyme 2). I
found
this discussion:
http://groups.google.com/group/aroma-affymetrix/browse_thread/thread/...
In the NetAffx annotation files, all probes have fragment length for
both enzymes, although they are sometimes quite large. The affymetrix
protocol says that the PCR works well for fragments between 200 and
1100bps. The annotation files for the Genome Wide SNP 6.0 arrays
annotate fragments up to 2000bps.
To use the aroma software, I want to modify the ufl file and set all
fragment length entries 45 or 2000 to NA. Unfortunately, I have
no
plan how to do this. Can someone point me to appropriate
documentation?
The how-to page 'Create a Unit Fragment Length (UFL) file' at
http://aroma-project.org/howtos/CreateAUnitFragmentLengthFile
should be useful. Make sure to not update the original UFL file, but
instead a renamed copy of it.
Bah, it's easier if I just write it:
# Get the UFL file
chipType - MOUSEDIVm520650;
ufl - AromaUflFile$byChipType(chipType);
# Get the pathname of the source file

[aroma.affymetrix] MOUSEDIVm520650 and CRMAv2
Hi all, I am using the Affymetrix MOUSEDIVm520650 chip. During the the normalization step for fragment length, the aroma software complains that no probes for enzyme 1 only exist (the same for enzyme 2). I found this discussion: http://groups.google.com/group/aroma-affymetrix/browse_thread/thread/880d164e7af6a849/3277e2d8870be696?lnk=gstq=Mouse+diversity#3277e2d8870be696 In the NetAffx annotation files, all probes have fragment length for both enzymes, although they are sometimes quite large. The affymetrix protocol says that the PCR works well for fragments between 200 and 1100bps. The annotation files for the Genome Wide SNP 6.0 arrays annotate fragments up to 2000bps. To use the aroma software, I want to modify the ufl file and set all fragment length entries 45 or 2000 to NA. Unfortunately, I have no plan how to do this. Can someone point me to appropriate documentation?
