Error in checkGeneSymbols(markers_all) : could not find function "checkGeneSymbols"

[lbbars]

Hello,

I'm trying to re-run the same analysis I performed some months ago and now I find this error when I start the sc-type analysis (function gene_sets_prepare). I am a little bit confused and I was wondering if there is any change on the function that I missed.

I would be very grateful if you could help me on that.

Thank you.
Best,

Hi, did you load "HGNChelper" package as stated in the example, because I faced the same problem with you but got it worked after loading the package.
