Hi, I am interested to try out using sparse matrix table but I am a bit confuse about the workflow to properly load the data.
1> I noticed that
transform_gvcf should be run on a mt with only 1 column. That means if I have an individual gvcf I am god to go, but if I have a gvcf with multiple individuals, I need to select each column and transform it to its own sparse mt… am I right ?
2> If I get it right,
combine_gvcf take a list of sparse mt. That means if I get a sparse mt for each of my individuals at Q1, then I can combine them into one unique sparse mt using that function… am I right ?
3> Can I combine_gvcf incrementally ? let say I have 3 individuals. First I use transform_gvcf of individual A into A.smt and B into B.smt. Then I combine_gvcf of [A.smt, B.smt] into all.smt. Then I transform_gvcf of individual C into C.smt. Can I combine_gvcf of [all.smt, C.smt] into all.smt ?
