Taking largest (negative) number from column of coordinates and adding positive form to every other
Hello all,
I'm new to the forums and hope to be able to contribute something useful in the future; however I must admit that what has prompted me to join is the fact that currently I need help with something that has me at the end of my tether.
I have a PDB (Protein Data Bank) file which I have condensed to the following for ease of modification:
What I want to do is take the largest negative number from each of the three columns after the column containing nothing but '0' values (-26.712 in the first column, for example), and add the positive value of those single numbers to every single value in their respective columns. This is because I require that there be no negative numbers in the output.
I've tried all sorts of combinations of (g)awk, sed, grep in Bash, and various Python scripts (which I think is probably a more suitable language for this sort of task) but nothing has done it.
I'm still a relative newbie so am probably being ignorant about something obvious; please bear with me. Any help would be greatly appreciated.
