Dear Annchen, Do you get this error with a more recent stable version, e.g., 7.4.1? Cheers, /Eugenio

External Email - Use Caution Hello,

I'm running the longitudinal hippocampal subfields module in ~300 individuals - it ran fine in most but with 8 i'm running into an error with the right hemisphere, which seems to be similar to the one posted in this unresolved threadhttps://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg74844.html, though my exact error is:

In an assignment A(:) = B, the number of elements in A and B must be the same.

Error in SegmentSubfieldsT1Longitudinal (line 2148)

My environment:

$ cat $FREESURFER_HOME/build-stamp.txt freesurfer-Linux-centos7_x86_64-dev-20171219-d5d1e74

$ cat /etc/os-release NAME="AlmaLinux" VERSION="9.4 (Seafoam Ocelot)" ID="almalinux" ID_LIKE="rhel centos fedora" VERSION_ID="9.4" PLATFORM_ID="platform:el9" ...

I can tell which of the 6 timepoints each of the 8 subjects are failing on, and i don't see anything particularly different about the input images from the failing tp, so i'm not sure what's going on or where to begin troubleshooting. I have tried simply re-running and gotten the same result. Attaching an example log file.

Any help is appreciated - thanks!!
