Dear Doug,
I did just that. Here are the files again.
Thank you so much! I really appreciate your time and effort.
Sincerely, Ye

Hi Ye, can you run the command like this:
mri_glmfit-sim --glmdir lh.meditation_age.glmdir --sim mc-z 500 4 mc-z.positive --sim-sign pos --cwpvalthresh 0.05 --overwrite >&terminal.txt
Note the "&" after the ">". This will cause all the terminal output to go to terminal.txt which will help me figure out exactly what is going wrong

Dear Doug,
The command line is mri_glmfit-sim --glmdir lh.meditation_age.glmdir --sim mc-z 500 4 mc-z.positive --sim-sign pos --cwpvalthresh 0.05 --overwrite > terminal.txt Most output goes into terminal.txt except the following (which is not important anyways) INFO: ignoring tag Creator INFO: ignoring tag SUBJECTS_DIR INFO: ignoring tag SynthSeed reading colortable from annotation file... colortable with 36 entries read (originally /autofs/space/terrier_001/** users/nicks/freesurfer/**average/colortabel_desikan_**killiany.txt) reading colortable from annotation file... colortable with 36 entries read (originally /autofs/space/terrier_001/** users/nicks/freesurfer/**average/colortabel_desikan_**killiany.txt) reading colortable from annotation file... colortable with 36 entries read (originally /autofs/space/terrier_001/** users/nicks/freesurfer/**average/colortabel_desikan_**killiany.txt) *** glibc detected *** mri_segstats: malloc(): memory corruption: 0x2ff05b10 *** Please see terminal output and log file in attachment.

Thank you so much for your patience.

I tried 500 iterations (I am aware that people usually do >10,000), but the program threw a "memory corruption" error. I have freesurfer 5.3. My ram is 4.0GB and the virtual memory is 7.8GB. Would you please shine some light on what's going on? I can't seem to find an executable solution from the archive. Thank you very much!

You need much more than 5 iterations! If you are doing whole hemisphere analysis, then you can use the precomputed tables. doug On 09/24/2013 01:46 PM, ye tian wrote: > Dear Freesurfers, > Sorry for having posted an incorrect question.
