Author Name: Jason Stajich (@hyphaltip) Original Redmine Issue: 3313, https://redmine.open-bio.org/issues/3313 Original Date: 2011-11-15 Original Assignee: Bioperl Guts

Bioperl version: 1.006 Here are two error messages when I’m using this module to calculate Fu & Li’s statistics: Illegal division by zero at (the Statistics.pm file) line 359 Illegal division by zero at (the Statistics.pm file) line 376 A further tracking down shows that the first error happens when $n (sample size in the ingroup) equals 1 or 2, and the second error happens when $n equals 3. This is not really a bug though. I would suggest either in the original code, do a checking before the calculation (and skip the current calculation when $n == 1, 2, or 3 - rather than let the whole program die), or add a few lines of notes in the CPAN page.
