Off topic:Failed Due To Truncated File Or Corrupt Bam Index File Error When Downloading Bam File From Samtools

Question

[Pascal]

Hi. I'm trying to open a fragment of a bam file using "samtools view" but I get "failed due to truncated file or corrupt BAM index file" trying to do the following error:

samtools view -hb <ftp://ftp-trace.ncbi.nih.gov/1000genomes/ftp/data/NA12878/alignment/NA12878.chrom1.ILLUMINA.bwa.CEU.high_coverage.20100311.bam> 1:150,000,000-151,000,000 > NA12878.chrom1.ILLUMINA.bwa.CEU.high_coverage.20100311_150M-151M.bam
[main_samview] retrieval of region "1:150,000,000-151,000,000" failed due to truncated file or corrupt BAM index file

I've tried to let samtools downloading the bai file and also to download it myself beforehand but it always give me the same error.

Regards.
