External Email - Use Caution Hi,
Running recon-all on sag T1 post-contrast MRI (for archival study) on virtualBox with centOS7 and freesurfer 6. The virtual box runs on a windows server and is allocated 8 processors and 16 GB memory by the windows server on which it resides. A citrix share provides the bulk of our filesystem storage space (/cifs). This filesystem appears not to allow symbolic links, such as these: rh.white.H rh.white.K lh.white.H lh.white.K These are symbolic links to [lr]h.white.preaparc.[HK], and recon-all stalls at the step during which these symbolic links are created. If we run the process in our /home directories on a linux filesystem, all is well, and recon-all runs correctly. However, only 8 GB of disc storage space there, and we have ~100 subjects to process. We thought we'd just run ~10 subjects or so, then move their data to the /cifs filesystem, but those 4 symbolic links won't copy. Questions: 1. If we ignore this error and copy everything else to the /cifs filesystem, is that OK, since the recon-all is complete? 2. If we try to run a GLM contrast on all the subjects (e.g., compare 50 to the other 50) in the /cifs filesystem, where we have space to keep all the data in one place, will the inability to create a symbolic link in that filesystem crash our analysis? 3. One post suggested copying the linked files into the SUBJECTS_DIR directory, but that won't work on /cifs and isn't necessary on the linux filesystem; is there another workaround? Thank you so much for you any guidance you can provide, and forgive me if there's some easy solution I've overlooked. John John R.
