Hello!

I have downloaded the BiocManager "muscle" package, but when I try to use functions that would use the package, it says muscle is not installed/working properly. I was wondering if anyone could help me or direct me to a resource where I could find help.

Thank you, Carleigh Oberkfell

Here is the error message I get after using the command:

The function in question is from the package bio3d which is a CRAN package. Unfortunately there is a miscommunication here as it seems like there is a R package called muscle that is in Bioconductor as well as a system requirement muscle that needs to be installed on your computer and in your paths. The muscle that bio3d is referring to is not the Bioconductor package. You should check the http://thegrantlab.org/bio3d/tutorials/installing-bio3d instructions specifically the section for MUSCLE
