Data filtering

April 18, 2020, 07:39:01 AM

I would like to filter my data by R. However, I am very new in R.
Subtracting the blank spectrum
Filtering samples by QC
Subtracting the m/z lower than 3000.
Is there any good packages providing me these features? Of course with a good tutorial. I try to improve myself on R. But I am newbie

Hi onursenol,

Great to see ambition like that.
I guess it really depends on what data you are starting with. If raw mass spec data, I'd recommend XCMS. There are some tutorials on there and all over the web!
MSnbase works with xcms and contains a lot of useful functions.

I'd recommend taking a look at a recently published paper linked in here. It covers a lot of what's available.

Good luck!
