Hi all,

I'm collecting multi-echo data on a GE scanner and trying to separate each echo as a separate nifti file using DIMON. When I download the raw data from the dicom, unzip, and run through DIMON there are different numbers of volumes in each echo (ie echo1=151 volumes, echo2=153 volumes, echo3=155 volumes). I've done this in the past with data collected on a Siemens scanner, and all the volumes were 150. My processing pipeline won't work if the echoes have different volumes. Any suggestions? Here is the DIMON command:

Dimon -infile_pattern './*.dcm' \
-dicom_org \
-gert_create_dataset \
-gert_to3d_prefix $multi_echo \
-gert_write_as_nifti \
-gert_quit_on_err

Thanks!!
