    Hi Morgan Sparks,

    If GenomicsDBImport is having a hard time finding the indexes, you can specify them with the option --read-index. 

    Let me know if this solves the issue!

    Best,

    Genevieve

    Thanks, that makes sense. I thought about that when I was reading the documentation, but I was confused as to what exactly put there. My file map has 134 samples, so do I just direct --read-index to the directory where the indexes are or do I have to have some kind of corresponding index map or similar.

    I believe it should be a list in the same order as your samples

    As in 

    sample_name1 sample_name1.g.vcf.gz.csi
    sample_name2 sample_name2.g.vcf.gz.csi
    sample_name3 sample_name3.g.vcf.gz.csi
    sample_name4 sample_name4.g.vcf.gz.csi

    Or just

    sample_name1.g.vcf.gz.csi
    sample_name2.g.vcf.gz.csi
    sample_name3.g.vcf.gz.csi
    sample_name4.g.vcf.gz.csi

    I think the second option is correct. It would be that way for all the other tools, but GenomicsDB is a little different, so you might want to test with a smaller list to verify it works.
