I need to copy projectors from an empty room recording to others. But I run into the issue of not having the same channels. Before I start writing a process, I wanted to double check I didn't miss an existing way to do that.
Background: We have an issue with a bad MEG channel affecting neighboring ones with correlated noise. It's not too big and SSP works for cleaning it on an empty room recording. I'd want to copy this projector to all our data until the sensor is fixed (hopefully sometime this summer). I think right now the only way to do this is to import both recordings and do Standardize > Uniform list of channels, then save the projector and load it in the other datasets. Is that right or is there another way? Unfortunately, the channel names are not saved in the projector files, so I'll need to copy the projectors directly from the noise channel file.
