Filtering spectra within a particular RT range in each precursorMz? functions similar to filterPrecursorMz?

[gmhhope]

Could I easily implement filtering spectra within a particular RT range according to their character in the MS1 scan? Something similar to filterPrecursorMz?

Thanks,

I don't know whether this is the right one? Could you briefly comment on this? Thanks very much!

filterRt(sps_ms2, rt = rt_range) # rt_range should be in the unit of seconds?

Best,
Minghao

Yes, exactly, filterRt is the function that lets you filter Spectra by a retention time range (independently if the spectrum is MS level 1 or 2).
