Hi Todd,<div><br></div><div>That's an odd problem, I've never come across that before. Not sure where the problem is, but maybe we can figure it out with a bit more info. Judging from the sequence names, this is using the Siemens product sequence? Can you confirm that the acquisition matrix was indeed 128x127 on the scanner? Sounds like an odd (as in strange :) number to me. One other thing you could do is run 'read_dicom -all -csa FILE' on an individual DICOM file from the relevant series. I appreciate this not always easy to do, since the DICOM standard pretty much states that filenames should be meaningless... If you're struggling with that, this little command might help:</div>
<div><br></div><div>$ find /home/todd/CF002dicom/ -type f -print -exec dicom_filename -q {} \;</div><div><br></div><div>This will print the name of every file in the folder hierarchy, followed by a more readily interpreted filename suggestion if it is DICOM. That should allow you find at least one relevant file to run 'read_dicom' on, and post the results (make sure you remove all patient-specific information first though).</div>

I have been having trouble converting my DICOM files to .mif format using mrconvert. Once the DICOM series has been read, an error comes up saying that the acquisition matrix [ 128 127 ] does not fit into the DICOM mosaic. I was wondering if anyone else has
come across this problem and if there is a way around it? The error is shown below.<br>
Thank you in advance<br>
