Hi Hua,
The T2D converter is pretty finicky and the least tested of our converters, so I'll cross my fingers and hope it works for you. A peak picking filter for all ms
levels can be applied like:
msconvert data.t2d --filter "peakPicking true 1-"
For t2d data, you probably want to combine multiple t2ds into a single output file, so you'll probably want to pass the parent directory of a bunch of t2ds
instead of a single t2d.
For example, if you have files:
runId/1.t2d
runId/2.t2d
runId/3.t2d
and you run:
msconvert runId --filter "peakPicking true 1-"
That will give you a single file with all 3 t2ds named "runId.mzML" (or MGF).
