Hi Julie,

I am running offTargetAnalysis to find gRNAs and their off-targets in some sequences. For a couple of sequences, I got the following error message while the program was trying to find all hits in a particular sequence:

"Error in .seqlengths_TwoBitFile(x) : UCSC library operation failed

Calls: offTargetAnalysis ... seqinfo -> seqinfo -> .seqlengths_TwoBitFile -> .Call

In addition: Warning message:

In .seqlengths_TwoBitFile(x) : End of file reading 4 bytes"

Could you please tell me what the cause of this error message may be?

Thanks,

Joyce

Joyce, It seems to be related to the UCSC BSgenome package you installed. You might want to update it.
