Hi @stbmtx,
Can you include the full traceback? It seems like you cut it off before it includes the specific error message. Does your cluster compute nodes have internet access? It also is not clear from your command what your singularity/apptainer preamble looks like, which is important knowledge.
I think the full 1.0.0 release will take a few weeks since we want users to test it before making the official release. Your input would be appreciated if you have time.
You can also try the distortion group merge in 0.24.0+ if you are using the same dataset as your previous issue (--combine-all-dwis not recognized).
Best,
Steven
