R package for the relative quantification of proteoform positional isomers (QPI) from MS2 scan data
devtools::install_github("EMSL-Computing/isoforma-lib")
To get started, read our vignette
You may need to install pspecterlib separately, though it should auto-install
with the above command. If not, try the command below. Check that both packages
install with library(isoforma)
and library(pspecterlib)
. If one of the
packages does not install,
devtools::install_github("EMSL-Computing/pspecterlib")
The package has been succesfully installed on an Apple M1 Max using 13.6.1 and a Windows PC running Windows 11. We encourage users to please report any installation issues on the Github Issues page, and we are more than happy to help!
