Dirac target curve format

[Mike-48]

Does anyone have documentation of the Dirac target curve format?

I have written scripts to read, graph, and plot them, and I'm modifying some target curves arithmetically and rewriting them as new files, but Dirac Live says the new files don't have recognizable data. I can't find anything wrong with them by inspection -- I've even tried changing EOL characters, to no avail.

If any of our Direc experts has information or ideas that might help, I'd be grateful.

Curios. Any chance you could share one of these offending files?

User pinksoda on avs forum has software within his HTP-1 GUI that manipulates existing and creates new changed Dirac target curve files. He may be a resource for you.

@JStewart - Here is a file that Dirac Live won't accept (needs unzipping first).

Thanks for the reference to pinksoda.

EDIT: I found the problem.
It wasn't the header, but that some of my manipulations put the list of breakpoints not strictly sorted by frequency. Once I fixed that, no problem.

So I need to put a sort into my code, and perhaps eliminate any points very close together.

Thanks again.

Sweet. Sounds like a handy program.

It is for me. It's all programmed in R (a language for data manipulation and visualization), so usable by those who know R. I'm willing to share with those who do.

As a side-effect of this project, I found out how great ChatGPT can be to refresh the memory or provide working examples of programs. A huge timesaver, that!
