# TASK: To combine struct params and meta data for plotting
|
||||
# Input csv files:
|
||||
# 1) <gene>_all_params.csv
|
||||
# 2) <gene>_meta_data.csv
|
||||
|
||||
# Output:
|
||||
# 1) muts with opposite effects on stability
|
||||
# 2) large combined df including NAs for AF, OR,etc
|
||||
# Dim: same no. of rows as gene associated meta_data_with_AFandOR
|
||||
# 3) small combined df including NAs for AF, OR, etc.
|
||||
# Dim: same as mcsm data
|
||||
# 4) large combined df excluding NAs
|
||||
# Dim: dim(#1) - na_count_df2
|
||||
# 5) small combined df excluding NAs
|
||||
# Dim: dim(#2) - na_count_df3
|

# This script is sourced from other .R scripts for plotting
