delete informant symbols for one color in pgn

Hi
Does someone know how it's possible to delete informant symbols in a big pgn file, only for one color, (white, or black moves).
I want to use it to filter out main lines from pgn files created with obk2pgn
"PGN Output
Each variation in the original OBK file is output as a separate game in the PGN file. Each move is annotated according to the book score: 3 = !!, 2 = !, 1 = , 0 = ? ."
Than I put a extra ! for one color, with lgpgnmw. Open the pgn in a text editor and delete al !!! annotations. Than I convert the pgn to cbh, and create a search booster. Than I remove the games with !!, !, and ?! in the annotation.
I will end up with only the main lines where chessmaster 9000 added 3 dots to the variation.
I hope someone can help me with that.

Yes I have pgn-exract. I don't think it has an option to only delete comments for white (or black) moves. I know there is a option to delete all comments but that's not what I look for.

Could you post a sample game?

This is how the output of obkpgn looks like for a white book.

I would like to delete only the comments for black moves in this file. So I wil be able to search for games with ? or ?! annotation for the white moves in chessbase.

I think I have find a solution. I first ad a extra ! to the black moves. Than I search for ?! in a text editor and remove them. I wonder if it can be done without lgpgnmw. Luckily I stil have a copy of it somewhere.

Try this
move annotation modifier
Sample run:
Code: Select all
enter pgn filename? sample.pgn
enter color of move annotation to be removed (w/b) ? b
Done, see output file out_sample.pgn
Press any key to exit
Note:
Place your pgn file in the same dir with the move anno exe file
Sample output from your posted pgn file.

Here's a hacked-together Perl implementation:
Code: Select all
cat kk.pgn | perl -ne '
if (/^\[/ || /^$/) {print; next;}
for $token (split " ", $_) {
if ($token =~ /^[1-9]/) {$wtm = 1; print "$token "; next;}
if ($wtm == 0) {$token =~ s/[!\?]//g;}
print "$token ";
$wtm = 1-$wtm;
}
print "\n"
'
That removes markings for black. If you want to remove markings for white, use "if ($wtm == 1)". No guarantees, but it seems to work in the example you posted.

Thanks Ferdy for the tool move annotation modifier.
It works great!
Also thanks for the Perl implementation Alvaro. But I have no experience with Perl implementation.
