Hi Paul,

Thank you so much for the quick reply. I am  Be wonderful if this 
could get added to coot 1.0 also. I also have some additional 
questions/suggestions, though I am not sure how much time this will 
take to implement some of my suggestions.


 1. I tried running the script, but I get an error:

File "", line 1, in 

File "C:/Work/IpT/Cryosparc/HOLE/April_2022/Local/coot_hole.py", line 
4, in 


   with open(fn) as f:

IOError: [Errno 2] No such file or directory: 'hole-surface-dots.dat'



The script represents hole-surface-dots.dat. You need to have created 
that file first.


I placed the 'hole-surface-dots.dat' in the project folder as well as 
the coot folder, but I get the same error?


Do I need to modify the script to specify the location of the file? I 
tried the following:


fn = "C:\XXX\hole-surface-dots.dat" but again I get the same error.



the filename (fn) needs to be in the current working directory - often 
that is the directory from which you started coot.




 2. Would it be possible to add additional point to improve the
“guidance” of the path?



Yes, it's possible.



 2. Perhaps as part of a script?


All of Coot's HOLE functions are scriptable.



 2.  Currently the path tends to take less obvious paths because only
two points along the path can be specified,



It might be that - or it might be a bug. Or maybe the step size is too big.



 2. but I think this can easily be avoided if additional points can be
specified. This is a problem in my case because I have a
complicated ion permeation path which is not just a straight line.

indeed - from the figure that I attached, you can see that the algorithm 
is supposed to handle paths that are not straight lines.



2.


 3. Do I just need to cite coot and HOLE or also additional references
for the HOLE implementation?

Coot and HOLE would be fine. I don't think that I wrote it up formally 
(probably because it was largely (just) an implementation of Oliver's 
paper). I'd like it to carve out the path from a map and add arbitrary 
map caps - that might be worth a mention.




3.



 4. This is a nit picky one, but it would be great to clear the screen
for all the previous HOLE plots so I don’t have to reload the pdb
each time. Again this is probably more of a problem for me where I
have to run the script multiple time until I get the optimal path.
Probably not an issue for most.



Isn't this just a matter of undisplaying or closing the previous generic 
objects?



Paul.

[COOT] Joint Instruct-iNEXT Course - September 25-30 - Oeiras (Portugal)

Posted on behalf of Dr. Margarida Archer - ITQB NOVA (Oeiras - Portugal)


Dear colleagues,

A Joint Instruct-iNEXT Course "Integrating X-ray Crystallography, 
Nuclear Magnetic Resonance, Magnetic Resonance Mass Spectrometry and 
Electron Microscopy" will take place in September 25-30, nearby Lisbon, 
Portugal.


The main goal is to provide the basic concepts and hands-on applications 
of Macromolecular Crystallography (MX), Nuclear Magnetic Resonance 
(NMR), Magnetic Resonance Mass Spectrometry (MRMS) and single-particle 
analysis cryo-Electron Microscopy (EM) in structural biology. Their  
strengths, limitations and complementarity will be discussed to achieve 
integrative structural biology approaches to tackle challenging 
projects.


The participants will become acquainted with the technology catalogues 
provided by Instruct-ERIC and iNEXT-Discovery and will need to select a 
case study and prepare an access proposal to one of these platforms. The 
course is aimed primarily at PhD and early post-doc students and limited 
to 20.
