Download the v252f test dataset from this ftp area. Run it through as directed in the README file.
Then, create a .difx directory for each of the comparison datasets you want to check against. I suggest calling them “<sitename>IPP<IPPversion>_1.difx”. Then copy the tarball from the table above, place it in that directory and untar it.
Now you can test any pair of datasets by running diffDiFX.py <directory1>/DIFX_54626_005310.s0000.b0000 <directory2>/DIFX_54626_005310.s0000.b0000 –inputfile=example_1.input.
Please also upload your results into the table above! The uploader won't allow a raw DiFX file (it complains about the filename extension) plus everyone will be loading up files of the same name. So please first tar it, using a filename like <sitename>IPP<IPPversion>.tar.
