Need Help with Large PGN's

[jwes]

I think you can do all this in SCID (or probably with ChessDB) by creating a spelling.ssp file. The format is explained in the start of the file that comes with SCID. Spellcheck would then edit all your names for you and by changing the names of old versions from whatever to OLD_whatever you could easily filter out old versions.

[Vinvin]

Here's what I used to make the big (716 226 games) rating list ( see here http://www.talkchess.com/forum/viewtopi ... 409#331409 ) :

1. Remove annotations
- Use the 40H PGN Utilities -> http://www.hoflink.com/~npollock/chess.html

2. Edit engine names
- Textpad is very efficient to edit text files of several GB (!) -> http://www.textpad.com/

3. Combine the files
- You can use the "copy" command from the windows command line exemple : "copy file1.pgn+file2.pgn+file3.pgn bigfile.txt"

4. Remove games involving older engine versions
- The 40H PGN Utilities should do this too, see doc here : http://www.hoflink.com/~npollock/overview-40H.txt

My best,
Vincent

If TextPad works with large files better than NotePad then I will definitely
use it.

There no comparison possible between TextPad and NotePad !
(they should really change the name, "TextPad" sound to close to "NotePad" !)

[Norm Pollock]

Hi norm ! Thanks for your utilities.

I got a little bug some times ago when I removed moves from games : IIRC, it's when there's a comment "{}" on the same line as the results (in the end of the game), the program stop just after that and I lost the end of the file ... if you are interested, I can look to reproduce that ...

My best,
Vincent

Hi Vincent,

Please try to reproduce the problem and let me know which program it is, and all the facts about the problem. Preliminary possibility is that you may have messed up the comment braces when you removed something. I'll take a look.

[Adam Hair]

Thank you everybody for the suggestions. By delving more deeply into
Norm's suite of utilities and by using a vastly better text editor ( I'm using
NotePad++), everything is going quicker, easier, and more accurate.

[Vinvin]

I couldn't reproduced the exact bug I got under winXP (I'm under Win7 now)

Try this "truncate.exe file.pgn 1" for the next file ... the result is lost for the 3rd game (under Winxp the program stop and the file is cut)

Hi Vincent,

Let me start off by saying "thank you" for finding this. And I must say that you had me worried for a couple of hours. There definitely is a problem involving 3 of my programs ("truncate", "minPly" and "trim") with the above pgn file, and the problem is specific to the third game:

If you remove this game there is no problem. If your have this game alone, there is a problem.

The problem is all due to the fact there is no "space" character separating the comment on the last line from the result that follows. When I put in a space, there is no problem.

I thought of a way to "fix" the programs, but it would involve putting a space before every "{" and after every "}" in the file to make sure at least one exists. That would involve testing every character. Needless to say that would slow down the program immensely.

Then it dawned upon me, that not having a "space" character before and after a comment is probably ILLEGAL according to PGN Standards.

So I looked it up, and sure enough, it is ILLEGAL. Here is an excerpt from

http://www.very-best.de/pgn-spec.htm#5.

Code: Select all

 5. Commentary
Comment text may appear in PGN data. There are two kinds of comments. The first kind is the "rest of line" comment; this comment type starts with a semicolon character and continues to the end of the line. The second kind starts with a left brace character and continues to the next right brace character. Comments cannot appear inside any token.

Comments cannot appear inside any token.

Therefore,

{it seems both engines do not claim a draw at the 50 move roule}1/2-1/2

should be

{it seems both engines do not claim a draw at the 50 move roule} 1/2-1/2
