External Email - Use Caution Hello,
I have been collecting data on a 7T scanner, with functional EPI data collected with 1.5mm voxels, and I have been having an issue with some of our data where recon-all just hangs after producing only a small amount of outputs. For instance, it might get to a point where it has generated 5-10 of the “lh” left hemisphere outputs in the surf folder, and then appears as if it continues to run for hours or days but no other outputs get produced and eventually the process times out and quits. I estimate that this happens for about 5-10% of the participants we have collected so far. If it doesn’t work for a particular participant, it will do the same thing again if I delete their temporary working folder and any outputs and try to run again from scratch. This is not happening with data from the same participants collected from a 3T scanner with 3mm EPI voxels, with recon-all run at 2mm. The only difference is the resolution of the data and therefore the resolution at which we are running recon-all. Our 7T functional EPI data is collected at 1.5mm resolution, so for those scans we run recon-all at 1mm resolution. Do you have any advice for how to get these participant’s data to finish with recon-all at 1mm? Thank you, Mike Datko
