R environment.arp2gen allows simple file conversion from the arlequin genotype format to the genepop genotype format. Arlequin files can gave 2-digit or 3-digit allele records. No file size limit is imposed, however, system RAM is a limiting factor.
arp2gen(infile)arp2gen will write a .gen file to the same directory as the original .arp file. The output file will have the same name as the original infile, with the exception of the file extension, which will be .gen following file conversion. The original .arp file will remain unmodified.
