[BioC] Rsamtools Error: vector of negative length

[Christoph Bartenhagen]

Hello everyone,

I am experiencing a strange error, while reading (large) BAM-files (> 
2GB) in R with the function scanBam() in the Rsamtools package.
It stops saying "negative length vectors are not allowed".

I think my BAM-file is ok, because I can read it in small chunks like 
reads on positive strand first, then reads on the negative strand (using 
ScanBamParam). This might be a more general Error in R because it seems 
to occur in very different R programs.

Has anyone experienced this error?
I would really appreciate any ideas how to fix this problem or 
concerning the reason for this error (I don't really understand what a 
"negative length vector" is).

Thanks in advance
Christoph
