Re: [caret-users] crash of X KDE session

2006-12-06 Thread marco tettamanti

Hi John,
I have tried unlimiting the coredumpsize from a tcsh shell (as I was 
indeed using a bash shell and the coredumpsize was limited to 0 kbytes) 
but, for some reasons, even if caret crashes no core file gets written out.
All the display functions that I have tried out (rendering surfaces, 
overlaying metric maps and so on) seem to work fine. But I couldn't tell 
whether the problem is really limited to opening volumes, as I haven't 
tried out many other things.

I will try to upgrade the graphic card drivers!
Thanks!
Marco

Marco,

The creation of a core file may be inhibited.  So, make sure you are 
running one of the c-shell variances (enter the command /bin/csh or 
/bin/tcsh.  Enter the command limit.  If coredumpsize is anything 
but unlimited, do the following:


* Enter the command unlimit coredumpsize.
* Enter limit to verify that coredumpsize is unlimited.
* Run caret by typing ./caret5 but do not use gdb.
* Import the volume to get Caret to crash.
* Relogin.
* Enter the command gdb ./caret5 core.
* Type where at the gdb prompt and send me the output.

Are your able to load a surface into Caret5?

Have you tried updating your graphics card drivers?

Hi John,
I have downloaded caret5_exe_linux_debug and ran it, but strange things
happened... :-|
1) First, I ran the debug executable as caret5 -notext as you 
suggested: I selected File Import, and, wow! caret opened the file. I 
did the same

with File Open and it worked. Solved, I thought: must be the freetype
library. So I clicked on the upper right corner to quit Caret and,
whoops, the X session crashed.
2) Second, I started X again, and wanted to replicate this behavior. I
launched the debug caret5 -notext, choose File Import... Well, this time
the X session crashed at this point already.
3) Third, I followed your suggestion and typed gdb ./caret5 (the debug
version), choose File Import and the X session crashed. Unfortunately,
at rebooting there was no core file in the directory from where I
launched caret.
4) I have tried to re-download caret5_exe_linux_debug to check whether 
something had gone corrupted during 1), but Caret continued to crash 
right after a File Import command.


Thank you again!
Marco

Hi Marco,
We had a problem similar to this that had to do with the freetype 
library that is used to render the stereotaxic coordinates on the 
volume display window.  I have built a new version of Caret5 for 
linux that has an option, -notext, that will prevent Caret5 from 
trying to draw any text characters.
* Go to http://brainmap.wustl.edu/pub/john/marco/;.  Use the 
username pub and the password download to access the website.
* Download the file caret5_exe_linux_debug.zip.  This is a big file 
since it contains debugging information.  If it takes too long to 
download, download caret5_exe_linux.zip instead.
* Unzip this file which will produce the caret5 executable.  In the 
directory where you place the caret5 executable, start it with the 
command ./caret5 -notext.  Load a volume into Caret and see if 
Caret crashes.  If Caret does not crash after loading a volume, it 
probably means there is a problem with the freetype library on your 
computer (perhaps google freetype server crash.
* If Caret still crashes with the -notext option and you downloaded 
the debug zip file do the following:  Run the command gdb 
./caret5.  After about 15-30 seconds there will be a gdb prompt and 
enter the command run.  Load a volume into Caret.  When Caret 
crashes enter the command where at the gdb and send me the output.  
If your X session crashes, log back in, and, in the same directory, 
see if there is a file named core.  If there is a file named core, 
enter the command gdb ./caret5 core.  At the gdb prompt, enter the 
command where and send me the output.

Good Luck.

Hi Donna,
I have tried to use File: Open Volume Anatomy and Open Volume 
Functional on:

image.hdr

image.nii

as you suggested, but unfortunately they all cause the X session to 
crash.


Thank you for you help!
Best,

Marco,
Does the problem occur when you use File: Open Volume Anatomy (or 
functional) File to open the same file?
If so, does it occur if you convert the file to NIfTI and/or AFNI?  
I'm guessing it will (e.g., suggesting a display issue, rather than 
a file I/O issue), but it helps to be sure.  If you have trouble 
converting to another file format, then upload the file here, and 
I'll provide you the converted version:

Rebecca,

Can you upload your volume to http://pulvinar.wustl.edu/cgi-bin/ 
upload.cgi and we will see what is going on.  Please let us know when  
you have uploaded your volume and the name of the volume file.

Hi - I'm having a problem segmenting normalized scans.

I've got a very non-uniform volume (macaque, from a 4.7T w/ 0.5 mm  
voxels) and have used AFNI's 3dUniformize to correct these issues.   
However, when I try to segment the normalized data in CARET, it  
either gives me an error (usually that findBiggestObjectWithinMask  
failed in some way) or it simply crashes.


I can run a successful segmentation on the non-uniformized volume,  
it just requires a great deal of manual correction.  I'm doing the  
same processing steps for both the normalized and non-uniform volumes.


Anything I should try here?  I've tried to run several different  
normalizations and all of them cause segmentation to fail.


Please let me know what other information you need from me on this  
one.


-Rebecca
