The result files of the test cases (XXXXX-results.csv) have an inconsistent header line (in release sbml-test-cases-2010-10-06.zip). Some test cases denote the species values with a prefix "caseXXXXX`" and others don't.
For example the header lines of the first 20 test cases are:
00001: time,S1,S2
00002: time,S1,S2
00003: time,S1,S2
00004: time,S1,S2
00005: time,S1,S2
00006: time,S1,S2
00007: time,S1,S2
00008: time,S1,S2
00009: time,S1,S2
00010: time,case00010`S1,case00010`S2,case00010`S3
00011: time,S1,S2,S3
00012: time,S1,S2,S3
00013: time,S1,S2,S3
00014: time,case00014`S1,case00014`S2,case00014`S3
00015: time,case00015`S1,case00015`S2,case00015`S3,case00015`S4
00016: time,case00016`S1,case00016`S2,case00016`S3,case00016`S4
00017: time,case00017`S1,case00017`S2,case00017`S3,case00017`S4
00018: time,S1,S2,S3,S4
00019: time,case00019`S1,case00019`S2,case00019`S3,case00019`S4
00020: time,case00020`S1,case00020`S2,case00020`S3,case00020`S4
It would help a lot parsing these files, if one kind of referring to species would be used for all test cases.
This is definitely inconsistent. Our apologies for this. The "cases" variant arose from some of the old Mathematica code we used, and the names should be changed.
I just committed a correction to all the files in SVN. We'll issue a new release of the cases archive soon.
Thanks for reporting this.
This was fixed some time ago. Closing the tracker item.
