I've run into something that I need a bit of clarification on in the NiftiImage lib. Specifically in the updateNiftiHeaderFromDict method.
Line 238 of utils.py throws an exception if the data_type field is > 9. From my reading of the nifti spec and parsing of the raw header file, this field appears to be a char[10]. (char data_type[10]). Where'd the other byte go? -james On Mar 20, 2009, at 1:42 PM, Michael Hanke wrote: > Hi James, > > On Fri, Mar 20, 2009 at 01:32:30PM -0700, James Kyle wrote: >> Greetings, >> >> I'm writing an application that'll receive a nifti image over a >> socket >> connection.
