Hallo, i tried to install the GeneRfold package for R. Is it possible to use an older Version of the package ? I want to use a feature for CRISPRseek.

BiocManager::install("GeneRfold")

ERROR:

Bioconductor version 3.9 (BiocManager 1.30.9), R 3.6.1 (2019-07-05)
Installing package(s) 'GeneRfold'
Warning message:
package ‘GeneRfold’ is not available (for R version 3.6.1)

I would appreciate your help. Thank you very much.

Best regards and greetings from Germany,

Nils

That package was removed in Bioc 2.10, so hypothetically you could install R-2.15.0 and then use biocLite to get it, but that seems sub-optimal?

Thank you very much for your help. Unfortunately CRISPRseek just works with R (>= 3.0.1), hence an older Version is not an option for me. But i don't get why you have a function on the CRISPRseek package, that requires geneRfold. I am going to ask in another entry.

When I look at the source for CRISPRseek, I do see that geneRfold is mentioned on the offTargetAnalysis() and compare2Sequences() help pages, but it is not used in the source code; in your updated post, it will be valuable to show a reproducible example (e.g., by cutting and pasting the examples on the page of the function that shows the problem), as well as the output of the command sessionInfo().

Are you sure that CRSIPRseek requires geneRfold?

Here's what I see...

It does not require geneRfold at all. My code is working fine. I read in the CRISPRseek paper, that you can use the command foldgRNAs to get additonal information for your gRNAs, requiering the geneRfold package.....

If i set foldgRNAs = TRUE the output does not change and i do not get an ERROR.

I am new to bioinformatics and this forum, so i'm sorry if i ask the wrong questions.

best regards,

Nils

I got an answer from Julie Zhu in another entry.

Unfortunately, geneRfold has been deprecated. Please let me know if you really need to fold the gRNAs, and I will share a workaround.

I hope everything is clear now, thank you for your suggestions.

Best regards,

Nils
