# FIXME: change filename 2(mcsm normalised data)
|
||||
# to be consistent like (pnca_complex_mcsm_norm.csv) : changed manually, but ensure this is done in the mcsm pipeline

# Task: combine 2 dfs with aa position as linking column
|
||||
|
||||
# Input: 2 dfs
|
||||
# <gene.lower()>_complex_mcsm_norm.csv
|
||||
# <gene.lower()>_foldx.csv
|
||||
|
||||
# Output: .csv of all 2 dfs combined
