Hi Julie,

We have been running offTargetAnalysis on a large set of sequences. For some of the sequences, we ran into the following 2 kinds of error messages:

(A)

Searching for gRNAs ...
Error in .Call2("new_XStringSet_from_CHARACTER", ans_class, ans_elementType, :
key 69 (char 'E') not in lookup table
Calls: offTargetAnalysis ... XStringSet -> XStringSet -> .charToXStringSet -> .Call2 -> .Call

I checked the sequences affected by this error and did not see any 'E' in there. Could you please tell me what might have caused this error?

(B)

Building feature vectors for scoring ...
Calculating scores ...
Error in `$<-.data.frame`(`*tmp*`, score, value = c(0.0831847889825708, :
replacement has 405816 rows, data has 405817
Calls: offTargetAnalysis -> getOfftargetScore2 -> $<- -> $<-.data.frame

Could you please tell me what to do to correct this?

Thank you very much!

Joyce

Joyce, The post at an erro related with RNAStringSet seems to suggest that there are non-DNA characters in your input sequences. Could you please post a couple of sequences for me to reproduce the error you encountered? Thanks!

Hi Julie, Here are two DNA sequences that incur the error: seq1: ATGGCTTCACAGCTGCCTTTTCCTGCAGACGACTTCGGTATCTACTATGTCCT seq2: ATGGCGGATATGGAGGACCTTTTCGGGAGCGACGTCGACAGTGATGCTGAGCGTAAAG Thanks for your help!

Joyce, I tested the two sequences and both worked for me. library(CRISPRseek) library("BSgenome.Mmusculus.UCSC.mm10") FYI, I used CRISPRseek_1.18.0 and Biostrings_2.46.0.

Hi Julie, Thanks for looking into this issue for me. Before I received your response to my question, I edited the post and added another question (B) on a different error message. You might not have seen it. I copied it below: (B) *Building feature vectors for scoring ...* *Calculating scores ...* *Error in `$<-.data.frame`(`*tmp*`, score, value = c(0.0831847889825708, :* *replacement has 405816 rows, data has 405817* *Calls: offTargetAnalysis -> getOfftargetScore2 -> $<- -> $<-.data.frame* Could you please tell me what to do to correct this? Thanks, Joyce
