Hi,

We are acquiring DICOM data on a siemens skyra. When I convert the images with the following dimon command:

Dimon -use_last_elem -infile_prefix '*.IMA' -dicom_org -gert_create_dataset

I get the following message:

++ DICOM NOTICE: 7x7 Siemens Mosaic of 43 94x94 images in file

The images look fine, but I wondered whether I should be worried about this warning.

Thanks a lot!
