I am wondering how to extract the pan-genome families from the results of OrthoFinder2. In ref (10.1128/spectrum.02072-21), they said "The OrthoFinder output files (Orthogroup_ Sequences folder) were used to extract pan-genome families (the totality of all genes found across strains), core genome families (genes shared among all strains), accessory genome families (genes shared among more than one strain but not all), and strain-specific genes (genes found only in one strain)". However, the Orthogroup_Sequences folder is still too big, so I am wondering is there any method or package to analyze or extract the sequence data from the OrthoFinder to create the pan-genome families. Thank you very much!
