[Insight-users] reading a dicom series, problems

[Luis Ibanez]

Hi Ruby,

When you mix ITK and MFC,
           ...and found a problem....

The culprit must of course be MFC    :-)

...

The exception seems to be thrown when the reader
attempts to read one of the DICOM slice files.

It basically means that one or several of the
filenames that you are passing in your
"fileNamesVector" vector of strings simply does
not exist on the disk.

Please print out the filenames contained in your
"fileNamesVector" and post them to the list.

It is quite likely that in the process you will find
that the filename are constructed incorrectly.



   Regards



      Luis
