Summary: turn recombination counting on Argument: < 'on' or 'off' > Default: displays the current setting
Turning this option on activates the recombination-counting mechanism in the "scan" command. After each pedigree is scanned, the observed recombinations (and resulting distances) are shown for each map interval alongside the actual distance of the interval. When there are significantly more recombinants than expected in an interval or set of intervals, this can often indicate an error or errors in the genotype data.
At the end of the scan of multiple pedigrees, the overall count of recombinants in each interval is displayed along with the expected value for the entire data set. Recombination counts significantly higher than expected here can be an indication of a marker that is error-prone over multiple pedigrees or of an error in the entered genetic map (either in order or distance).
'Count recs' is ON when GENEHUNTER is started.
