I'm trying to write a script which takes .xls column entries (from a table of peptides), creates ranges of +/- 3 for each value, and then matches this range against another .xls file to return label information.
I've put together a step-by-step procedure for what I'm trying to achieve in "script_procedure.txt".
I've also attached sample files: "cropped_MB4_Elephant.xls"
Finally, Label_List is used for the script to extract the label information for START and END +/- 3 ranges and input these into a new column.
The attached text file should make clearer sense.
