Nrrd Library

This page describes the procedure for synchronizing the NrrdIO libary in Teem, with the one in Insight/Utilities/Nrrd

Note that patches may have to be moved in both directions.

Background

  • Nrrd started as one of the libraries in Teem <http://teem.sf.net>
  • NrrdIO is a subset of Nrrd containing only the IO functionalities.
  • The only part of Teem that's in ITK is in NrrdIO.
  • Creating NrrdIO from Teem is done by a GNUMakefile and a perl script.
  • The back-propagation that should happen is from NrrdIO back to Teem, because the idea is that NrrdIO should be periodically regenerated from Teem.

Checking out NrrdIO

Use the following SVN command

  svn co http://teem.svn.sourceforge.net/svnroot/teem/NrrdIO/trunk NrrdIO


This was generated in the Teem side by

  • running a "pre-GNUmakefile" gnu makefile, which also uses a little perl script unteem.py.
    • The comments in pre-GNUmakefile explain this some.

Update Procedure

Perform the following two tasks:

From ITK to NrrdIO

For all the changes made to

             Insight/Utilities/NrrdIO

after the last Nrrd batch commit, understand what the change was, and then apply the same change to either sourceforge's NrrdIO or even better, to Teem itself.

This is probably not a one-day project.

From Nrrd to ITK

Gradually or all at once, depending on our bravery, we copy sourceforge's NrrdIO to

           Insight/Utilities/NrrdIO 

and see what breaks,... and fix it
