FALCOR

Fluctuation AnaLysis CalculatOR
"The program FALCOR is a web tool designed for use with Luria-Delbrück fluctuation analysis to calculate the mutation frequency and rate from various mutation assays in bacteria and yeast (e.g. resistance to canavanine or erythromycin, reversion to Trp+, etc.)."
This tool was originally developed as a Java Applet (no longer supported by browsers) by Hall et al, 2009 and has now been updated to Javascript by the Liang Lab.

The original background descriptions and instructions on the tool can found here.
