Hi David Will do so, thank you! That makes a lot of sense. I have also added the mzXML files but this might be the cause of the discrepancy I see! Thanks Shagun On Friday, March 25, 2022 at 4:42:46 PM UTC-4 David Shteynberg wrote: > Hello Shagun, > > I noticed in your condition file you are us

Hello Shagun, I noticed in your condition file you are using TMT10 with the following masses: The difference between neighboring channels is <0.01 at the lowest and yet you are using tolerance of 0.2: I think the appropriate mass tolerance for t

Hello Shagun, Also please include your mzML files, which contain the actual data that Libra quantifies. Thanks! -David On Fri, Mar 25, 2022 at 10:34 AM David Shteynberg < david.shteynb...@isbscience.org> wrote: > Please place your files on a shared drive and send me a link. > > On Fri, Mar 25,

Hello Shagun, Thank you for your email and interest in the TPP. I have recently been comparing TMTPro analysis by ProteomeDiscoverer and Byonic to that produced by TPP's Libra. As far as I can tell, when I run and compare the quantities (intensities) they are mostly the same between Libra (witho

Hello Our lab has been trying to use Libra to quantify MS2 (Ion-trap) identification and MS3-based quantification of TMT datasets and we were trying to benchmark with an artificial yeast and mammalian spiked dataset with known fold-change (FC) values. However we observe drastically different v
