MS-DIAL / DIA-PASEF
Dear Hiroshi, Dear All

I am trying to analyze DIA-Pasef data (plasma lipidomics, RP-UHPLC) with MS DIAL v4.80
I have followed the usual workflow suggested for IMS-DIA, but I have basically 0 hits. Do I am missing something?
The same samples were analyzed with DDA-Pasef, and everything worked.
Thank you in advance for your help
Best
Eduardo

THANK YOU IN ADVANCE
