HELP WITH GENEPOP

OPTION 8 Miscellaneous Utilities
(adapted from the original Genepop v3.1b documentation)

Sub-option 1

This sub-option computes the maximum likelihood estimates of gene frequencies when a null allele is present, using the EM algorithm of Dempster et al. (1977). Estimated allelic frequencies and estimated numbers of homozygotes and of heterozygotes with a null allele are indicated in the output. GENEPOP considers that the allele with the highest number in the dataset is the null allele. For example, if you have 4 alleles plus a null allele, a null homozygote individual should be indicated as 0505 in the input file. If you do not have at least one null homozygote in your dataset, this sub-option is useless.

Sub-option 2

This sub-option "diploidizes" an haploid data set. For example, the line "popul 1, 01 02 10 00" of an haploid dataset with 4 loci, will become "popul 1, 0101 0202 1010 0000". The new data set is returned via the web browser (or email) which you can save as a text file.

Sub-option 3

This option takes data files with 3-digit allele entries and converts it to a file with 2-digit allele entries. The web version of Genepop will do this automatically if you choose the '3-Digit Alleles' option on the browser form. However, we provide this utility in case you wish to use the dos version of Genepop in order to verify results returned from the web version, or to use options not yet available here.

Results for all sub-options are returned via your web browser which you can then save to you local machine. You may also choose to have them emailed to you.

Please report any problems or bugs that you encounter with the web version of this option to Eleanor Morgan
