change dicom field from float acquisition time to human readable format
Hi, all Some private dicom field : 0019, 105a tells a mri sequence duration. Unfortunately it's in float, like 5.145648e+07 An idea would be to modify this header to x min y sec.
I end up my search with a strftime like conversion, but really don't know if there is a trick to use it (or another option) in my exiftool command line ?
The nirvana would be recursively search in a database directory all new dicom files (less than 5 min) and change the 019,105a from Float to a x min y sec.
The filesystem tasks are possible via the OS, but find out if exiftool superpower is able to achieve directly my Nirvana is way beyond my great exiftool experience with pictures files.
Any idea ? Many thanks
