Fwd: Delete lines containing a specific word

[Francesco Pietra]

I forgot to add that the lines to strip are in present case of the type of the
following block

HETATM 7007  O   WAT   446      27.622  34.356  55.205  1.00  0.00           O
HETATM 7008  H1  WAT   446      27.436  34.037  56.145  1.00  0.00           H
HETATM 7009  H2  WAT   446      27.049  33.827  54.563  1.00  0.00           H

occurring in a 300MB file.

In present case each three-lines block is followed by line renumbering (7007,
7008, 7009 are line numbers). So, the script is simply to strip the lines
containing :WAT".

In other cases the block is intermediate. Therefore, a second script would be
useful where the line that follow the block are renumbered, e.g, line "HETATM
7010" following the above block renumbered "HEATM 7006".

thanks
