Hello, I am trying to run Surface Group Analysis with Qdec, but am stuck on the "make_average_subject" step. I have run this command on four subjects in my virtual machine and everything is fine. However, I have 13 subjects and there is not enough room in the virtual machine for them. I have moved my subjects to the C drive after running all the appropriate commands. I set the environment to the C drive from the virtual machine, but the make_average_subject does not complete. This is the error: writing update template with 13 subjects to lh.reg.template.tif... TIFFLinkDirectory: Error fetching directory count. TIFFWriteScanLine: lh.reg.template.tif: In place update to compressed TIFF images not supported.. TIFFWrite: TiffWriteScanLine returned error curvature mean = 0.003, std = 0.572 curvature mean = -0.081, std = 1.818 Protocol error Segmentation fault Error:make_average_surface
In addition, since I am out of space, is there any way to increase the size of virtual machine disk image? We are using the Xubuntu Virtual Box as recommended on the FreeSurfer installation webpage. Thank you in advance, Kristina
