Title: Data filtering
Post by: onursenol on 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!
