samtools: parse error in SAM to BAM

[anaqib2]

Hi

I am trying to convert .sam file to a .bam file using the following script:-

samtools view -bT Ref_HighCov_B07.fa Reads.sam > Reads.bam

And the error I get is this....

[sam_header_read2] 116 sequences loaded.
[sam_read1] reference '' is recognized as '*'.
Parse error at line 1: missing colon in auxiliary data


Kindly help
