Don't start analysis again if a game contains analysis data already

[Zaoliang]

At moment Katrain starts analysis after a game has been loaded.
This keeps user waiting a while, depending on games progress or moves.

I would like see the analysis data can be used directly and analysis just start from last move or new move.

If it is needed for a re-analysis of a game for some reason, then please don't make this as default.

I agree. Currently there is no way to access saved analysis data when loading a previously analysed game. All that is shown is the data from the re-analysis.

If you have the 'save analysis in sgf' box tixed in 1.7 it should save it.
Other than that, having 'fast visits' low, even at 1, makes fast loading near instant.

@sanderland 'save analysis in sgf' ? I use vsion 1.7 already. I checked menu and analysis but I cannot find this option.
Thanks!

@sanderland I tired this Cache analysis in SGF. No changes than before. Low the value to 1 for 'Show stats if mocre than..visits' doesn't help in my case.

[sanderland]

What did you try? Save a game with analysis and then load it?

Show stats if more than..visits' just changes which dots are solid with text vs small and faded

General/Engine settings has the visits thresholds

[Zaoliang]

@sanderland Yes, I saved changes with anaylsis and then reload my game.
I tried now with low visits value in General/Engine settings, but this has no effect on behavior of analysis.
I mean it just starts analysis from beginning.

[sanderland]

@Zaoliang what exactly are you doing?

• new game, play
• save
• load the resulting sgf

should load analysis

• load downloaded sgf
• analyze
• save
• load

has a bug which is fixed in 1.7.1

max visits should affect how much analysis is done. (fast visits if drag+drop or ticking 'fast' in load should be very quick with 10 visits!)

[Zaoliang]

@sanderland load downloaded sgf, I see the difference. Thanks for your explanation!

yes, fast load option is useful, thanks again.

I'm having this issue, even with "Cache analysis in SGF".

What I'm doing is:

1. Load SGF file
2. Wait for analysis
3. Save SGF with analysis
4. Close Katrain
5. Reopen Katrain
6. Load SGF with analysis

What I get is a new analysis, and all the analysis I've made before is not accessible.

[Zaoliang]

@Azirine So I can reduce waiting time with load option 'Use fast analysis' :)

@Azirine So I can reduce waiting time with load option 'Use fast analysis' :)

The problem is not the waiting time. When I set fast analysis with 1 visit, all that is shown is the analysis with 1 visit, even though I've done thousands of visits on every move before and saved it.

[sanderland]

@Azirine yes that's a bug that will is fixed in the next version. You can kind of work around it with 'save as', I think. Otherwise it forgets to save the analysis format version, and on loading it's like "wrong version, ignore!"

fix released
