Hello,
This sounds like it might be worth me trying to debug that data file, but
I guess it's so huge that it would mean DVD (i.e. real mail) transfer
rather than http to get it over here.
The Ansig contours format was changed for Analysis (for one thing to deal
with negative contours the same as positive). So the two are incompatible
and we definitely haven't tried to allow the old contour files to be read
in.
It would be good if we could get to the bottom of this.
