Creating EPD from PGN leaf nodes

[PaulieD]

Looking to simply convert PGN to EPD, but it needs to be the ending pgn positions (leaf nodes) not every move like PGN Extract GUI does.

I have Python 3.4 installed and Ferdinand's PGN sorting tool. Can a simple bat file be creating to convert any pgn file to EPD with ending FEN? PGN Extract Gui does not allow switches to be added to the GUI commands.

This comes to mind. Does it help?

Sounds like a good task for Python Chess:

This is more complex than what I am seeking. I saw this with the eval and so on.

This is the right idea. I just need a bat file or python script, I do not know how to do that, I only have Python because I needed it to use a tool from Ferdinand.

The following batch script:
pgn2fen %1.pgn -e -l |sort|uniq|leaf>%1.epd

You supply the batch file with the name of the pgn file (without the pgn extension) and it will create a file of leaf records.

Sample session, running batch against file baracuda.pgn :
Q:\>makeleaf baracuda

Q:\>pgn2fen baracuda.pgn -e -l | sort | uniq | leaf1>baracuda.epd
Error loading PGN: Error: Line 5157: Unexpected End-of-file
{This is a spurious error message and it can safely be ignored}

The -l parameter is a lower case 'L' and not a '1'...
Q:\>type makeleaf.bat
pgn2fen %1.pgn -e -l |sort|uniq|leaf>%1.epd

Here I use tail the display the records at the bottom of the file:

Q:\>tail baracuda.epd
rnbqkb1r/p4p2/2p1pn1p/1p4p1/2pPP3/2N2NB1/PP3PPP/R2QKB1R w KQkq - fmvn 9; hmvc 0;

send me a pm and I will send you a copy of leaf and uniq if you like.

To get the last epd record of each game of a pgn file, use pgn-extract in combination with epdFin (within 40H-EPD utility suite, see www below).

"epdFin" is used in combination with the excellent utility tool
"PGN-Extract" by David Barnes. Together they input a "pgn" file and
output an "epd" file containing a user-specified number of records
from the end of each game. The default is 1 record.

Using the default (1 record), the output will be the final "epd"
record of each game.

Example: PGN-Extract -Wepd -s -otemp.epd alpha.pgn

epdFin temp.epd

Afterwards, you can use epdTrim to remove opcodes, and you can delete temp.epd.

Ok,
Here is my EPD.bat file

PGN-Extract -Wepd -s -otemp.epd TopGM_2move.pgn

epdFin temp.epd

How do I use the epdTrim with the outF.epd end product?
Thanks
