[vtkusers] error message reading (Mac-created?) DICOM files in a Windows app

[Steven Chall]

Mathieu,
You're absolutely correct.  I should have taken the error message at its face value:  using Cygwin to look at the directories in question from a Unix perspective, there are indeed .DS_Store directories in each, that came over with the .dcm files from the Mac on which they were stored.  They simply didn't show up in Windows.  Thank you very much.

Steve,

  Here is your query:

...
queryDICOMReader->SetDirectoryName("C:\\Users\Steve\\Documents\\IMRT\\CT
queryDICOMReader->\\Patient013\\Primary");
...

  Here is your warning:

...
vtkDICOMImageReader (03110268): DICOMParser couldn't parse :
C:\Users\Steve\Documents\IMRT\CT\Patient013\Primary/.DS_Store
...

  So I suspect that this directory actually exist on the machine your are running your vtk filter. And in this directory there is a hidden unix file called '.DS_STORE', which I suspect is coming from an archive (.zip, .tgz) created on a MacOSX system.

HTH

The mystery for me in this case is that it's trying to load files in a directory that doesn't even exist on my machine, and I don't think on any Windows machine (I don't believe Windows supports files or directories whose names begin with '.').  I'm trying to figure out why it's appending ".DS_Store" to the path I give it, then failing to parse the resulting string, then moving on to successfully loading the files in that directory that do exist.  Any ideas?  Thanks.
