Yes, this is almost certainly Elena's issue.

The AFNI file format is such that you can have multiple sub-bricks within the same file (e.g., multiple types of summary group statistics). These show up as separate "columns" or menu picks in the drop-down menus. But when doing segmentation, you typically want Label = Filename, so you have to enter the change in both places.

Elena,

I believe that all you have to do to fix this issue is to change the 'Volume Label' which is located at the bottom of the Save Data File pop-up. You'll can change it to whatever you want but changing it to the File Name usually makes thing less confusing. The Label name is what appears in the drop down menu from the D/C.

Let us know if that is not the fix you needed.

Thanks,
Erin

Well Caret is not having any more problems with memory or crashing, however, I do notice after I remove handles and save the file (renaming it as instructed to segment_errorcorrected_fix1 from segment_errorcorrected) I am not prompted to select that recently saved file (...fix1) as the volume file to use for my next segmentation. My choices only include the previously saved volume files but not the most recently saved file, though I can locate it in my working directory. I simply cannot access it as an item in the drop down menu for the second segmentation as is shown in the tutorial. Please direct me as to how to remedy this as I am certain the difference in which file is selected isl affecting the result of the segmentation. Thank you and have a great day.

Just a couple of things to add to John's reply:

* Most users who segment using Caret, 1Gb of memory is enough, but if
your volume is very high resolution or otherwise is very large (e.g.,
dimensions of 300x300x300 are above those of a typical Caret user; most
volumes are something like 150x200x150 or smaller in size). During
processing, Caret has multiple volumes in memory concurrently.

* Once at least a year ago, I saw this error when the user's real
trouble was disk space. He was working on a network drive that wasn't
big enough for the intermediate files. Try running it in a local drive
with gigabytes of free space (several times your volume size).
