Step/increment issue #46

Closed Brainpiercing closed 6 years ago

Brainpiercing commented 7 years ago

I'm trying to do an optimization of all kinds of parameters for data from LC-Orbitrap-MS, and IPO gets stuck in a loop on the ppm step for centWave. I want to optimize between 1 and 3 ppm, and it's actually trying 2.7 and 4.7 ppm and just switching between those two non-stop.

So I'm guessing there is an issue with the step size for incremental optimization when small steps are necessary.

Thank you for sharing this issue. Can you reproduce this behaviour with data from some package (e.g. faahKO or msdata)?

@Brainpiercing How about your issue? Can you provide more info? (e.g. the output from IPO, the sessionInfo() and in the best case also your data)

Due to no updates for several months, I'll close this issue. If there are any new infos, you're welcome to reopen the issue.
