Hi Rick,
thanks for the advice.
I've ran your suggested script on one sample folder, which contained 6 runs of 86 images, and 1 localiser run of 5 images (I know this from using a Dicom viewer program). Your initial script suggestion provided 7 dimon files of varying sizes (from 9 to 86 files, with only one 86). Then I tried inserting the -dicom_org option and it couldn't seem to get past the localiser scan, so I manually deleted these 5 files from folder, and then ran the same script again and it appeared to work as it should. I received 6 dimon files, all 86 images in size.

So I have two questions, can you think of a reason why the localiser (a 5 image temporal localiser/scout scan) might be causing Dimon to stall (it hung for 30 seconds without doing anything before I ctrl+c out, each time I tried it before removing the relevant files). And, if Dimon can't handle it, is there an option to not process these particular files?

I'm happy to upload a sample, how much do you want? Can you point me to the directions on uploading.

Cheers
Rob
