MeCuP (Melting Curve Profiler) is a tool for thermal protein profiling - it supports screening and identifying candidates in thermal proteome profiling experiments. Please visit this Excel file as a one stop for instructions on how to use MeCuP, explanations about possible arguments to pass by filling a csv template when using MeCuP.
Please ensure when filling the csv template that there are no changes due to formatting some entries to dates!
MeCuP was developed in a way that it can sit in and is functional in an ARC (Annotated Research Context). It was initially developed in and to be usable in the DataPLANT PLANTdataHUB. The ARC provides a data management solution developed by DataPLANT the NFDI4Plants (NFDI = National Research Data Infrastructure). For underlying schemata, metadata annotation and making use of many other features and benefits of an ARC, please visit the DataPLANT website.
Please note, the CITATION.cff, requirements.txt and citations_for_R_RStudio_requirements.txt files would not regularly sit at the base of an ARC.
This repository contains the MeCuP scripts and a minimalistic directory structure and explanations for all required files for the use of the MeCuP script. Data and an example for the use of MeCuP will be available with the associated submitted manuscript (see citation below in this README).
It comprises the default settings with low resolution plots for MeCuP when using R with RStudio and the option "1" in the respective RStudio prompt. These settings are minimalistic and suggested for routine screening application.
A higher resolution of plots can be selected for selected proteins subsequently or, if desired, directly when running MeCuP. These are selected for when using option "2" in the RStudio prompt. NOTE: this roughly doubles the required storage. Also, the time per run increases when using a higher resolution.
The option "3" that can be selected in the RStudio prompt is only provided for development. Here the settings have to be provided and are extracted directly from the script.
Plot settings can be customized. Please be aware that this requires some experience. It is strongly recommended to use the pre-set settings.
After screening for candidates with a MeCuP run, users can provide a list of selected proteins for which they need plots in publication resolution (300 ppi) e.g. for publication, presentations, reports, etc. This list has to be provided in the first column of a csv file using the protein identifiers exactly as provided in the output of the respective MeCuP screening output run directory corresponding to the first majority protein IDs. An example is provided here.
tbc - Please note, MeCuP regularly produces a session file.
