Reference genome to create intervals list

    Hi Priyadarshini Thirunavukkarasu,

    It is important that the interval list that you use for exome data corresponds to the same exome capture targets. The Broad's exome intervals lists are specific to the custom exome targeting kits used at the Broad, so they may not be suitable depending on the prep kit used for your data. I would recommend getting the appropriate intervals list from the specific sequencing provider that your data is from. 

    Kind regards,

    Pamela

    Hello

    Can I use the interval list from this link https://console.cloud.google.com/storage/browser/_details/gcp-public-data--broad-references/hg38/v0/HybSelOligos/whole_exome_illumina_coding_v1/whole_exome_illumina_coding_v1.Homo_sapiens_assembly38.targets.interval_list;tab=live_object

    But, the interval file from the above link has both GRCh38 and Hg19 intervals. Please advice. I want interval list for Genomic build GRCh38

     

    Thanks

    Hi Priyadarshini Thirunavukkarasu,

    In the link you shared, I only see the GRCh38 interval lists so this should be what you are looking for. Please let me know if you are seeing an issue when using this interval list.

    Kind regards,

    Pamela

    I want intervals list for GRCh38. The below excel file was from this link (for GRCh38) but it also shows intervals from Hg19:

    https://console.cloud.google.com/storage/browser/_details/gcp-public-data--broad-references/hg38/v0/HybSelOligos/whole_exome_illumina_coding_v1/whole_exome_illumina_coding_v1.Homo_sapiens_assembly38.targets.interval_list;tab=live_object

    Hi Priyadarshini Thirunavukkarasu,

    I'm not sure why you are seeing "hg19" in this excel file or where this excel file came from, but the interval lists should be for hg38. Can you find any interval in this file that is only applicable to the hg19 reference build and not hg38? The interval list should work for hg38 and shouldn't have any intervals that are exclusive to hg19.

    Kind regards,

    Pamela
