[Insight-users] ERROR: GDCMImageIO: could not open file...for writing

[Luis Ibanez]

Hi Verena,

The code that generates this error message is quite straight forward:


Insight/Code/IO/itkGDCMImageIO.cxx : lines 160-170:

>   os.open( filename, std::ios::out | std::ios::binary );
> 
>   if( os.fail() )
>     {
>     itkExceptionMacro(<< "Could not open file: "
>                       << filename << " for writing."
>                       << std::endl
>                       << "Reasion: "
>                       << itksys::SystemTools::GetLastSystemError());
>     return false;
>     }
> 

Can you please post to the list the *exact* filename
for which you are getting this error message ?


   Thanks



      Luis
