Mike, Finally I figured out the problem. It is not a bug. It is the searching criteria max.mismatch =5 and filtering criteria min.score = 0.5. If you set max.mismatch = 5 and min.score = 0.1. The summary file will be there. What happened is that with your initial parameter setting, there is no off-target found. Maybe I should have the function to print out “No off target found with your searching and filtering criteria”. Best regards, Julie On 8/4/14 11:03 AM, "Brodsky, Michael" wrote: Hi. I tried two more tests. First, I ran the same script on Rstudio on the cluster. The cluster packages are all the standard (not development) version of R and do not give the Warning message for R version 3.1.1. So, it is NOT due to using a different version of R for the packages. Second, there is only one target site in the fasta file, so I also ran it with find gRNA = TRUE. This gave the same problem where the summary file does not list any gRNAs.

I got a good off target file, but the summary file is blank. I have attached the input file and the command set. The session info is below. I got a warning that I used a more recent (developer?) version of R to construct the packages. Do I need to uninstall and reinstall these? thanks, mike Warning messages: 1: package ‘CRISPRseek’ was built under R version 3.1.1 2: package ‘Biostrings’ was built under R version 3.1.1 3: package ‘IRanges’ was built under R version 3.1.1 4: package ‘GenomeInfoDb’ was built under R version 3.1.1 5: package ‘GenomicRanges’ was built under R version 3.1.1 Warning messages: 1: package ‘GenomicFeatures’ was built under R version 3.1.1 2: package ‘AnnotationDbi’ was built under R version 3.1.1 R version 3.1.0 (2014-04-10) -- "Spring Dance" Copyright (C) 2014 The R Foundation for Statistical Computing Platform: x86_64-apple-darwin10.8.0 (64-bit) R is free software and comes with ABSOLUTELY NO WARRANTY.
