Hello freesurfer experts,
I am trying to use an occipital lobe template adapted to my data as several surface and volume files, and there seems to be a problem with the surface files. Whenever I try to open a surface overlay (in .mgz format) in freeview this error comes up;
freadFloat: fread failed freadFloat: fread failed ... [0]PETSC ERROR: ------------------------------------------------------------------------ [0]PETSC ERROR: Caught signal number 11 SEGV: Segmentation Violation, probably memory access out of range ...
When I try to convert this file to nifti format a seemingly similar error comes up;
(...) mri_convert rh.template_areas.mgz AU_areas_template_rh.nii.gz mri_convert.bin rh.template_areas.mgz AU_areas_template_rh.nii.gz $Id: mri_convert.c,v 1.226 2016/02/26 16:15:24 mreuter Exp $ reading from rh.template_areas.mgz... TR=0.00, TE=0.00, TI=0.00, flip angle=0.00 i_ras = (1, 0, 0) j_ras = (0, 1, 0) k_ras = (0, 0, 1) writing to AU_areas_template_rh.nii.gz... NIFTI FORMAT ERROR: nslices 117239 in volume exceeds 32768
I have tried to debug but failed so far. Has anyone come across a similar problem and do you have an opinion onto what might be causing this? The same adapted template's volume files work just fine.
--I am using Ubuntu 16.04& freesurfer v.6
Thank you so much! Idil
