Dear All
I am trying to use GATK for multiple samples SNP calling. The requirement of input sequence reads file of GATK is 1) .bam 2) indexed 3) coordinate sorted 4) with read group including PL (platform) and SM (sample tags).
I am writing to ask if it is OKAY for me to use the output bam file of tophat as the input file of GATK.
I utilized the samtools to view the output bam file of tophat. The first several lines are as follows:
HS5_204:6:1206:11794:144840 99 scaffold_1 12632 3 19M117N81M = 12775 243 GTCTGTGATGACCAAAGAGGGGAAGTGGCAAATGTCCTTTGTCATGCCATCCAAGTACGGCGCTAATCTGCCTTTGCCCAAGGATCCAACTGTGAGGGTT @<@DBDDDHFDFBHHIIIICBA@8?:C@DADHIE?:?BE*??DFFBGD>D?FDGICF<@;8:9=AB:@CDCC>CCCCCC@BB?5AC?@@CCA:AC@BBB8 AS:i:-9 XM:i:2 XO:i:0 XG:i:0MD:Z:1C43A54 NM:i:2 XS:A:+ NH:i:2 CC:Z:scaffold_16 CP:i:9083845 HI:i:0
Do anyone have idea if i still need to do the index and sort of the bam file with samtools or picard? If so, that would be a lot of work.
Thanks in advance!

Metagenomics has improved the way researchers study microorganisms across diverse environments. Historically, studying microorganisms relied on culturing them in the lab, a method that limits the investigation of many species since most are unculturable1. Metagenomics overcomes these issues by allowing the study of microorganisms regardless of their ability to be cultured or the environments they inhabit. Over time, the field has evolved, especially with the advent...09-23-2024, 06:35 AM -
During the COVID-19 pandemic, scientists observed that while some individuals experienced severe illness when infected with SARS-CoV-2, others were barely affected. These disparities left researchers and clinicians wondering what causes the wide variations in response to viral infections and what role genetics plays.
Jean-Laurent Casanova, M.D., Ph.D., Professor at Rockefeller University, is a leading expert in this crossover between genetics and infectious...09-09-2024, 10:59 AM
