Hi Tim and Matt, Yes using Mac OS 64bit - Sorry Matt subject number was 118730. I think Tim is right in saying this is an issue that crops up (excuse pun) with FSLview.
I just re-checked the 10 subjects QC’d in fsleyes and all is well! Apologies for the scare!!

This sounds like a problem I recall from older versions of FSL, where our timeseries were larger than the integer types they were using to compute the data index, and thus near the end of the timeseries, it suddenly started grabbing voxel data from the beginning of the file, but with a large shift (because the 2^32 limit doesn't line up nicely with a multiple of the frame size).

In particular, volumes 1089-1200 are misaligned - please see image attached for subject 118347. I haven’t checked all the subjects but it does appear to be consistent across the 10 that I randomly selected for QC. Its relatively simple to exclude misaligned volumes but I was wondering whether this was known (apologies if it has been mentioned previously in the mailing list).
