OK, I've downloaded your files and replicated the error. It might take a few days for me to actually figure out what's going wrong. I'll let you know when I do.

ps. I'm not sure about the source of the file drop system. Feel free to ask our sys admins by sending email to help@nmr...

Looks like the machine I was running it on before was still running a dev version from February, but I just tried it again with the latest stable version (see below) and got the same thing.
I've uploaded a tar file with all of the dicom files. It also includes a script of how afni does the conversion and the nifti output from it.
Thanks, -Adam
PS. I like your filedrop utility. Is it freeware or something you wrote in house?

I'm not sure what's going on with this -- I don't have too much experience with GE functionals. Can you tar it up and put it somewhere I
can get or send it thru our file drop system? The file drop is at: https://www.nmr.mgh.harvard.edu/facility/filedrop/index.html.
Also, what version of mri_convert are you using? You can check with mri_convet --all-info

I seem to be having some trouble converting a 4D time series from dicom to nifti format using mri_convert. Rather than outputting 144 frames of 38 slices each, it creates a volume with a single frame of 5472 slices (see below). Is there an argument I should be using to specify number
of
frames?
I think there was a post on this back in April (http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg02656.ht
