EOF marker is absent. The input is probably truncated.[bam_header_read] invalid BAM binary header (this is not a BAM file)

[U201412486]

Hi, I use bwa to produce a bam file.When I handle the bam file with other program，it report error below:

[bam_header_read] EOF marker is absent. The input is probably truncated. [bam_header_read] invalid BAM binary header (this is not a BAM file). Segmentation fault (core dumped)

Any advice? Thanks.
