Build a syngraph from BUSCO data, allowing for missingness

syngraph build -d directory_of_tsv_files -m -o test

Model fissions and fusions over a tree, record rearrangements using taxon_1 as a reference

syngraph infer -g test.pickle -t newick.txt -r 2 -s taxon_1 -o test

Model translocations, fissions and fusions over a tree

syngraph infer -g test.pickle -t newick.txt -r 3 -s taxon_1 -o test

Input data

When inferring rearrangements, input data should only contain markers from chromosome scale sequences as unscaffolded contigs will result in excess fission events being inferred.

If using BUSCO data, tsv files should be named My_taxon.\*.tsv where My_taxon is also a leaf in the newick tree. The file should contain the first five columns in the *full_table.tsv file generated by BUSCO (Busco_id, Status, Sequence, Gene_Start, Gene_End). E.g.:
