Hi NITRC!

I am currently using WFU PickAtlas 3.0 with SPM8 under MATLAB R2012A.  I have noticed that, while I am in the 'WFU_PickAtlas Results" window, I will occasionally (and somewhat inconsistently) be able to save reports.  For the times when I cannot save reports, the following error is produced in the MATLAB prompt:

Saving page 1 as Color PostScript in file /Users/reynaadmin/Desktop/BrainLabels.ps

Is there anything that I might be doing incorrectly, or is there any specific part of the codebase that I could look into modifying to fix this?

Best,
John

Hi John,
  There are two items in the log you provided.  I would assume the saving error is from the 13:01 timestamp.  The later one looks like a unexpected shutdown of the viewer or pickatlas.

Does the saving report happen on the same types of reports?  For example, is it always BrainLabels?

Ben

Hi Ben,

I have only been using BrainLabels, but have tried tweaking the report settings to determine if that is a factor at play.  With the files whose reports don't save, I haven't had any success saving BrainStatistics or using different atlases.  It appears as though the reports refuse to save regardless of what their content is.  The content is rendered correctly in the viewer, however.  I have also tried switching the file format of the exported file from PS to the other possible formats, with a similar error.

Many thanks,
John

Hi Ben!

I appear to have fixed the problem- it looks to be that the paths above a certain length (I simplified the path in the example error so that it would be shorter) were not being saved to, so I saved the PostScripts to a directory one level higher with success.

Many thanks for your aid once again,
John

Thanks for letting me know.  I'm curious what the length of the file name was that you were trying to save.  Also, did it potentially have non-friendly characters (spaces for example) in it?

Ben

Hi again!

The path definitely had spaces, as well as a period in the middle of a directory name ('Spm.mat files').  The length of the path name without the file was 169 characters (a nice 13^2, although that's probably coincidence).  With the file name included it was 217 characters.
