Thanks Doug,
I am not running out of space. I did delete the analysis and it did not help. Anyhow, I jsut upgraded my freesurfer to freesurer 5.1 to see if the issue is resolved with the new version.

Hi Maryam, it looks like there is a corrupted file there. Did you run out of space on your disk? If not, have you tried to delete the analysis and rerun? You might also try adding -no-fwhm (I can't remember if 4.5 takes this option). doug

Hi,
I am encountering a memory allocation error with selxavg3-sess and I am not sure how to get around it:
Here is the lines that I am running mkanalysis-sess -analysis FHPDM_noauto -TR 2 -paradigm allpara.par -designtype event-related -funcstem fmc -motioncor -runlistfile FHPDM_runlist.txt -inorm -nconditions 8 -timewindow 20 -TER 2 -polyfit 2 -mcextreg -noautostimdur -force
selxavg3-sess -s 110821_xu_FHPDM_02 -df sessdir -analysis FHPDM_noauto It is a single subject data with 12 runs, event related design that each event last for about 4 seconds and the total experiment time is 328 seconds( at TR=2 is equal to 164 TRs)
My computer is a MAC with 4 gb of ram. and I am running freesurfer 4.5. I have ran similar analysis on the same number of runs but much longer events (12 sec) before and have not had a problem. This is the first time I am analyzing data for this particular experiment though. Here is the error line that I get:
mri_fwhm(2138) malloc: *** mmap(size=16777216) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug MRIalloc(70, 70, 33): could not allocate 19600 bytes for 49364th slice

Can anyone help? Thanks, Maryam
