This channel is a repository of videos and how-to guides on topics related to the Proteomics and Bioinformatics related to Proteomics. If you have requests or questions please inquire at IDEAProteomics@uams.edu.
A quick look at using the Spectronaut viewer for DIA projects
Dennis Province, from the IDeA National Resource for Quantitative Proteomics, spends a few minutes explaining how Spectronaut can be used to look at Data Independent Acquisition projects. This free viewer, which can be requested at biognosys.com/software/viewers/ can be used to look at (*.sne) files. Every DIA project from the National Resource will contain one of these files.

TINSTAAFL - Instrumentation for DIA - Rick Edmondson
Переглядів 394 місяці тому
In this video Rick Edmondson from the IDeA National Resource for Quantitative Proteomics talks about the different parameters that affect the quality of the data in a DIA experiment. Chromatography is key and the MS parameters must be set to reflect the peak width. Scan speed, size of the DIA window, and the range of the DIA windows can all be adjusted. Rick reminds us that there is no such thi...

As part of downstream analysis e.g. reactome, I need to use the protein IDs or gene names from my raw data. These downstream analysis dont work when there are multiple IDs per row hence they need to be separated with each protein having its own value. Since there are multiple IDs per row, do you assume that the Reporter intensity corrected value for each protein or gene in a given row is the same?

Pretty neat video, it helped me get started with TMT data! Thanks!
Glad it helped!
@@ideanationalresourceforqua4640 I was looking for such a video for setting up MaxQuant for Ligandomics/Immunopeptidomics datasets, is there one available? I couldn't find it.
@@ideanationalresourceforqua4640 I'm wondering if you have such a video for MaxQuant setup for Immunopeptidomics data?
@@ideanationalresourceforqua4640 I've another question, do you use the "Reference channel" column in the experimental design/Raw files window? I'm wondering if this is an optional feature to be used only when multiple sets of TMTn plex are used in a single experiment?
I have been intending to answer this but the short answer is no... if we are doing non-specific digestion we use a program called Peaks. I have not tried this on MaxQuant.
Hi, from where we take the data which we use as a input?
What i would like to know is how to generate that result file. Where can i learn that?
I have forwarded this on to Stephanie. Thanks for your question.
github.com/ByrumLab/proteoDA Here you go.
Thanks@@ideanationalresourceforqua4640
Hi Denis! With 30 processors, approximately how long does it take to complete you MaxQuant runs (per .raw file)? Thanks!
It takes 30-45 minutes for a single ratiocheck raw file. Several hours for a 6 or 10 plex.
In this video, you did not give the fraction numbers in the though there are multiple (18 fractions) fractions. I am curious, was this omitted intentionally? Kindly give insight.
Sorry for the delay to your question. You are correct, this project was offline fractionated and then 18 superfractions were made from the 46 fractions that our 60 minute gradient provides. Each of these 18 superfractions were ran on the Eclipse and the raw files for each of these were then imported into MQ for analysis. Most TMT experiments will have some offline fractionation to increase depth, ours happens to be 18. The file names have the fraction numbers included and the lysates were in a different experiment than the phospho enriched fractions. Does that answer your question? I could provide a video explaining the process of fractionation if anyone is interested.
@@ideanationalresourceforqua4640 Thank you for getting back to me. If you can kindly make a video regarding the fractionation, that would be very helpful. Particularly for bioinformatician who are not confident with the wet lab experimental setup. Thanks!
I am working on this! Thank you for your patience.

thanks Mr. Dennis Province. this has helped me a lot.
Looking for how to run MaxQuant analysis on TMT-10-plex fractionated samples [Paper - Archer et al, Medulloblastoma]
@@ideanationalresourceforqua4640 yes sir/madam, i am interested, it would be really helpful. I actually want to run MaxQuant ptm (Phospho (STY)) analysis on the phosphoproteome mass spec raw files.
There is about one minute of blurring during this presentation. It was intentional
