Is it possible to source and read bam files directly from ftp site into Unified Genotyper without downloading them first. This option works in samtools view -- but if I try the simple straightforward way in GATK (just replacing the -I inputfilename.bam with -I ftplinktobamfile.bam ) it does not work. Is there another way of doing this? This would save me a lot of diskspace if I could do this.
Hello, I am a first-time user of GATK and have spent some time now on trying to get the input bam files in the appropriate format. To run IndelRealigner, I have added ReadGroups, Reordered and Index my bam file with the respective Picard-Tools.
My command-line is the following:
java -Djava.io.tmpdir='pwd'/tmp -jar GenomeAnalysisTK.jar -I ./add_read_groups_reorder_index.bam -R ./genome.fa -T IndelRealigner -targetIntervals ./gatk.intervals -o ./*.bam -known ./Mills-1000G-indels.vcf --consensusDeterminationModel KNOWNS_ONLY -LOD 0.4
I get the following message:
SAM/BAM file /home/gp53/tophat2-merge-ctl-1st-2nd-readgroups-reorder-index.bam is malformed: SAM file doesn't have any read groups defined in the header.
My reads are paired-end aligned with TopHat2 I will appreciate your help on this. Thanks, G.
