Romulo:
1) Perform image resampling if the spacing of the MHD file doesn't match the slice thickness found in the reference dicom series. Use the dicom spacing as the output.
2) Remove files from the dicom series if the number of slices in the MHD doesn't match the number of files in the image (it may be smaller due to rounding of image resampling). An error is still generated if there are more slices than files, though.
- issue: VV somehow still detects all images (Open Dicom), but the number of files and the series itself are correctly read.
3) Warnings are printed in both cases above if "verbose" is enabled.
