Hi all, I'm trying to use tabix to index a custom, tab seperated file I have for fast access. The file is formatted such that the first 3 columns (tab seperated) represent a chromosome, start point, and end point respectively. It then has 4 more columns, each holding a number. The file is sorted and bgzipped. I have tried every combination of tabix commands I can think of (specifying start and end points, trying to format it like a preset file to use the -p option) but keep getting some version of tbx_index_build failed. I'd really appreciate any troubleshooting help/advice.
