[Insight-developers] Re: Proposal: Change default DICOM fromDICOMImageIO2 to GDCMImageIO

[Mathieu Malaterre]

Jim,

	I am not sure I understand this. GDCMSeriesFileNames first goal is 
really to order a series of dicom files. Let say the proper ordering is:

AA.dcm, CC.dcm, BB.dcm (*)

	Now user would set the input directory, then retrieve the ordered files 
(GDCMSeriesFileNames::GetInputFileNames()), then to preserve the 
filename convention would set output directory, and GDCMSeriesFileName 
would write in this directory using the same 'file-'naming convention.

	In your solution how do you differenciate the input directory from the 
output directory ?

Mathieu
(*) This correspond to the case where the filenames are the UID and 
therefore alphabetical ordering is different from the real ordering.
