Is there a way of analysing .gam files in GNU ? I have tried several
different paths but nothing is working or do i need to get a new

.gam files should import the same way as Jellyfish match files (.mat) or
Snowie standard text files (.txt), because they really are the same
thing, except they just contain a single game.

I'm working to sort the problem out.
.mat files have a line at the beginning stating how long the match is,
.gam files do not have this line. .mat files have the player names in
name-1: score-1 name-2: score-2
.gam files do not have associated scores.
The .mat import function searches for these two lines and will not
accept a file without them, so .gam files won't be imported. I want to
change the parser to accept these as well.
In the meantime, you could use a text editor (not a Word Processor) to
put an initial line on the file:
0 point match
for a money game
5 point match for a game from a match
Then on the line with the player's names, add the current scores,
preceded by a colon ( : ) For example:
Fred : 0 Zoe : 0
Now you can import the file as a .mat file

Tried this tip. Edited with notepad. It didn't work.
Any real tips? Thx in advance.

Here is a procedure someone kindly sent to me. I've used it successfully.
1- Find an existing MAT file that GNU handled successfully. A match of 7 or
more points is preferable.
2- Feed this MAT file, not the GNU output, into your favorite text editor.
Don't use MS-Word or any other word processor. If all you have for text
editing is Notepad, it's clunky but it will work. Rename it with Save As.
3- Change the match length on the top line to 61. Too much larger, and GNU
instantly crashes. Too much smaller, and you start seeing odd cube
"errors", such as doubles that GNU says are correct at 17 to 11 that
would be wrong for money. (You can set the match length to 0, but you'll
have to remember to turn Jacoby off if you're importing GammonEmpire/Play65
games. -- Ian)
4- Open the first GAM file you wish to process in a separate window. Shade
the area from immediately before the final period to the beginning of the
line right below the players and their scores. I've found trying to import
the player names line causes problems, so I stopped trying to save time by
doing this. Ctrl-C.
5- Go back to the MAT window and shade the same area of the first game.
Ctrl-V. You can then (carefully!) change the player names by shading and
typing over. Don't mess with the spacing, this is always a bad idea with
MAT files! Be sure you have the player names in the right order. If the
ending says "Wins X points and the match", delete "and the match". Save.
6- Repeat this procedure with the next GAM file. You can now wait to
change the player names until all the files are embedded in the MAT, since
you have already done the first one to show you whos who. It's then easy
to change them all at once when youre finished, using Copy and Paste. You
can change the players' scores to suit the results of the preceding
embedded GAM files, and you'll probably prefer to do so, but this is
unnecessary to make GNU run the MAT.
7- If you run out of games in the original MAT before you run out of GAM
files you want to embed, choose a short game and copy/paste it several
times in the middle of the MAT file. I find it works best to avoid using
Game 1, but I do use one where Ive already changed the names and deleted
"and the match". If the spacings look wrong, go back to your last saved
version and try again. Don't exceed about 16-18 games per pseudo-MAT file,
because GNU and especially Snowie are likely to crash if you load too many
games in one shot. If I want to run a longer session, I run it in sections.
This isn't all bad, since it provides information regarding how well my
opponent and I played as the session progressed.
8- If you have too many games in the MAT for the number of GAM files,
delete the last games from the MAT by starting your shading at the end of
your last embedded GAM file, right before the period, and ending the
shading right before the MAT file's final period. It's best never even to
click the mouse after that final period!
9- Save, then run with GNU or Snowie.
This may seem like a lot of trouble, but eventually you'll get the
procedure down, and I think you'll find the resulting analyses helpful and
accurate. You will find it easier to do the second and subsequent ones,
since once you have one pseudo-MAT that works, you can use it for a
template for the others.

Here's a pretty simple working solution. Basically, what was missing from
Jim Segrave's initial solution was a line that says " Game #".
So, you need to edit the .gam file to include three header lines:
" X point match" (0 for money session)
" Game #" (MUST have this leading space)
" player1 : (score) player2 : (score)"
What's handy about this method is that it allows you to combine all of the
games from one session into one file. Just cut and paste all of the
different game records into one file; include the three header lines
before each game; adjust the game # and scores for each game; and save as
.gam or .mat.

It copies .gam files to .txt files, which can be imported to GNU
