Error when trying to set maxdetphoton from CLI

[Marco Nabacino]

Dear Dr. Fang,

I'm having trouble setting the maximum number of detected photon when running mmc from the command line.

If I don't set it at all:

mmc -f input.json -d 1

the simulation runs fine.

If I set the -H flag like this:

mmc -f input.json -d 1 -H 10000000

then the simulation doesn't run, and I get the following error:

MMC ERROR(-1):incomplete input in unit mmc_utils.c:2669

If I move the -H flag before the -d flag:

mmc -f input.json -H 10000000 -d 1

then the simulation runs, but it ignores both flags, so that no detected photon data is outputted.

Finally, if I move it as the first flag:

mmc -H 10000000 -f input.json -d 1

mmc interactively asks for the simulation parameters (total photon number, RNG seed, source position etc.), rather than reading the json.

I've also tried using --maxdetphoton instead of -H and changing the number, but the result is still the same. I'm using MMC v2024.2 on Ubuntu 24.04.

Thank you very much,

best,

Marco

Thanks Marco, you were right, there is a bug in -H handling, I have just fixed it

Because the current nightly build is broken due to

Please either use mmclab to get around this or locally build your binary with the break statement added.

Dear Dr. Fang,

thank you for the prompt response. I built the binary locally with the fix and now it works!

Thanks,

Marco
