Manual

To run IBD-Groupon, from the command line:

java -jar IBDGroupon.jar -i num_of_individuals -f pairwise_ibd_file -c chunk_file

-i: num_of_individuals: the number of individuals your data set has.

-f: pairwise_ibd_file: the input pairwise ibd file, which should be the output ibd file from Beagle. The index of the two haplotypes of the same individual should be individual_index_1, individual_index _2, respectively.

-c: chunk_file: the maximum IBD chunks. You need to identify the chunks according to the pairwise_ibd_file yourself.

output: the group-wise IBD tracts for each chunk. Notice we consider the IBD tracts among the haplotypes instead of indivdiuals.
