Dear Edward. I am about to setup a new test branch for using nmrglue. I would need to compare all intensities in a long range of spectra. I will setup a new branch by: http://wiki.nmr-relax.com/Git_branch_creation I already have some test code, which is working. I am a little unsure where this will be going. But essentially, I would like to write some wrapper functions to nmrglue, which can be handsome. Best Troels Emtekær Linnet
