Hi,
Sorry for off-topic, but I do need some suggestions now,
Here it's
# RAAADUE AA STBBCCCRE BP1 BP2 ACC N-H-->O O-->H-N
N-H-->O O-->H-N TCO KAPPA DDPHA PAI PZI X-CA Y-CA
Z-CA
1 174 V 0 0 0 0, 0.0 11,-0.3 0,
0.0 9,-0.1 0.000 360.0 360.0 360.0 155.8 21.7 42.5 31.0
2 175 H - 0 0 0 9,-2.2 7,-0.7
1,-0.1 2,-0.1 -0.345 360.0-101.3 -55.9 135.5 19.9 41.2 27.8
What if I only interested what under the N-H-->0?
How to took this column out.
It doesn't have a fixed Field No, (not matter from the left or right).
So I don't know how to get it by awk.
Let's radically trim your example to get rid of line wrapping artifacts.
# RAAADUE AA STBBCCCRE BP1 BP2 ACC N-H-->O O-->H-N
1 174 V 0 0 0 0, 0.0 11,-0.3
2 175 H - 0 0 0 9,-2.2 7,-0.7
From this it would appear (assuming all white-space is space character) that one could search the heading for appropriate label (i.e. "N-H-->0") returning its position (N). Then search for next non-space character following a space returning the position of the last space character (M). Then for each line return the sub-string from character N->M, trimming as desired.
What that would be in awk I have no idea as I've never used awk. HTH
