Ignoring channels in statistics

[FengqiuAdamDong]

Hello!
We are trying to use this for CHIME/Pulsar filterbank style data and was wondering if there was a feature similar to -ignorechan from rfifind. We have many channels that have been 0'd out prior to rficlean.
I noticed that using the -pcl flag makes rficlean take the first channel and use the statistics on that, which is not desirable as that could be one of the zeroed out channels.

Hi Adam, there is no feature similar to -ignorechan. The -pcl flag doesn't use the first channel for statistics, if this flag is there then it checks (within every block) whether all the data values for an individual channel are same (could be 0s or anything else) or not. If it finds all the values same, then it skips some of the processing on those channels. So, in principle, this flag should be usable in your situation but to be frank this particular functionality might not have been tested out that thoroughly as there were not many use cases.
