Upload your file. Otherwise, you will see the example data.
Currently HaDeX is limited to `cluster` files from DynamX 3.0 or 2.0 and `tables` file from HDeXaminer. The supplied file should contain at least two repetitions of the measurement for the uncertainty to be calculated. If the supplied file contains modified peptides, maximal exchange control cannot be applied.
Please be aware that loading data (including example file) may take a while. Thank you for the patience.
If the file contains both modified and unmodified version of a peptide, they are treated as different ones.
For the program to behave correctly, please make sure supplied file fulfills all requirements. Requirements can be displayed by clicking the button.
Values chosen here are propagated into all of the tabs for coherent results.
Differential plot presents the uptake difference between State 1 and State 2.
The axis ticks have the same size as the axis label. The legend text size is the same as the x axis label.
The empty values (e.q. `Frac DU`) mean there was not sufficient data for this peptide. Abbreviations from the table: DU - deuterium uptake, Frac - fractional, Theo - theoretical, U(value) - uncertainty of value.
The empty values (e.q. `Frac Diff DU`) mean there was not sufficient data for this peptide. There is a possibility that the measurement result is available for only one state of the peptide. Abbreviations from the table: Diff DU - differential deuterium uptake, Frac - fractional, Theo - theoretical, U(value) - uncertainty of value.
Volcano plot presents the uptake difference between State 1 and State 2.
The axis ticks have the same size as the axis label. The legend text size is the same as the x axis label.

If you are interested to dig more into the world of HDX-MS, please see the following:
Manually curated lists of software, publications and other resources related to the analysis of HDX-MS data. It is community-maintained and new items are added when noticed. It is a valuable resorce to explore HDX-MS and what is done by the scientists from different labs.
List can be found here.
Feel free to fork the repository and add things you found valuable that are missing from the list.
The R-packages that allows super-fast isotopic envelopes simulations based on the algorithm by Zhong-Yuan Kan due to the usage of Markov chains. The functionalities of the package are will be available soon in a form of a GUI.
