    Problem with the article Hello, everybody. I'm getting my Master's Degree in Biomedicine, and i'm trying to do phylogenetic analysis of Rhodiola rosea to prove the hypothesis that my region's phenotype is best producer of salidroside. I'm planning to use available data from NCBI and other open sources. For phylogenetic analysis I'm considering choosing matK, MYB genes; I tested MEGA for basic phylogenetic analysis using those genes from different Rhodiola rosea species and also form other Rhodiolas. I need to hear some criticism from people who worked with plant's bioinformatics, phylogenetics. Any advice would be much appreciated! Thanks! submitted by […]

    Hello everyone! I have a few questions about using DDA acquisition mode on a Waters Vion IMS QTOF to perform plant metabolomics. Does anyone here have experience with this instrument? I’m planning to test DDA both with and without ion mobility, but I’d really appreciate insights from people who have run it before. In particular, I’m wondering about: Scan time you typically use Collision energy settings — do you apply a fixed CE regardless of m/z, or do you use a low→high CE ramp? Whether you normally enable ion mobility during DDA or prefer to keep it off Any practical […]

    Hi. I work with natural product isolation and analysis. I have .d format files and mestrenova. How do I proceed with them for dereplication? submitted by /u/Technical_Magician_6 [link] [comments]

    Hi, im working to bridge the gap between the unknowns of metagenomics and metabolomics. lots of limitations but if anyone has worked on a data repository or knows of one that has information of microbes and their produced list of metabolites/ source of sample for metabolites that would be great. Thanks in advance submitted by /u/Mental_Position4608 [link] [comments]

    Hi all, I only have the final LC–MS feature Ă— sample table exported from Bruker (MetaboBASE / HMDB library) — I do not have the raw.d or full chromatograms. After alignment, I found that the same compound name / same formula / same adduct / same MS/MS library can appear at several different RTs. Right now I see three situations: MS/MS confirms it’s the same compound, but RT is far apart e.g. “4-Dodecylbenzenesulfonic acid” matched to the Bruker MetaboBASE library at RT 1.17, 6.52, and 14.37 min. MS/MS confirms it’s the same compound, and RT is extremely close (a few […]

    TL/DR: A lightweight Python package for finding molecular formulae given a mass + error window. No databases required – generates all possible elemental compositions. I put this together and I'd like to share it with people who might find it useful. What find-mfs is a simple Python package for finding molecular formulae candidates which fit some given mass (+/- an error window). It uses Böcker & Lipták's algorithm for efficient formula finding, as implemented in SIRIUS. find-mfs also implements other methods for filtering the MF candidate lists: Octet rule Ring/double bond equivalents (RDBE's) Filtering by predicted isotope envelopes Note: This […]

    I’m looking for feedback from metabolomic researchers to improve a biomedical research data portal. I’ve set up a 5-minute test where you can evaluate the quality of a few sets of search results. If you have 5 minutes, your feedback would be super useful to me. Here’s the link if you’d like to participate: https://app.lyssna.com/do/hybewv501lsj/qub2al I really appreciate the help! submitted by /u/GeronimoJackson-42 [link] [comments]
