an error I had not seen before

FYI: In checking over the error.log from the protein we just finished, saw (only once):

ERROR: [001.013] {randwalk.c, line 3878} Discriminant <0 (-0.000007) while calculating CB

As long as this happens only rarely, it's OK. Its a floating point rounding error basically, and shouldnt affect overall results significantly if at all.
