Script which extracts a single numerical columns from a text file while ignoring headers. Will convert numbers in scientific notation into floating point notation.
This is especially useful for pulling data out of CAMPARI or GROMACS output files for further analysis. The nice thing is it carries out numerical conversion implicitly - meaning you can take data which is in scientific format in a file and floating point format are dropped out.
Say you want the energies
colgrab -f __ENERGY.dat
will print each energy line to STDOUT.
Example - GROMACS energy
colgrab -f energy.xvg
will print each energy line to STDOUT.
