Repeated positions provided in simulation output

[MattHartfield]

Hi, I noticed that some positions are repeated in the output file, so two different polymorphism states are assigned to the same location.

Minimal example:
discoal 30 1 110000 -t 550 -r 110 > all_sims.out

Then obtaining positions and showing duplicates:
sed -n 6p all_sims.out | awk -F ': ' '{print $2}' | awk '{for(i = 1; i <= NF; i++) printf ("%.6f\n",$i)}' | uniq -D

Hi @MattHartfield -

this is about the accuracy of the printf formatting. If you'd like to turn it up for greater precision you could alter the makeGametesMS() function in discoal_functions.c and alter line 2079 to something like

fprintf(stdout,"%.9lf ",allMuts[i] );

that will print up to 9 digits to the right of the decimal place. run make again and you should be all set i believe.

generally if this is biting people I'm happy to update the discoal code

Hi! That works better now, thanks for the quick reply!
