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.

File status:

                      

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.

File from HDeXaminer detected!

Some of the information from the data file requires your confirmation. For the additional information on how the data from HDeXaminer is processed, check the requirements above. Keep in mind that the MHP value is generated based on the peptide sequence and therefore, may differ from actual value in case of the modifications.
The calculated values of MPH might slightly differ based on data used and its precision. Used amino mass data

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.

This function plots the change in the uncertainty of deuteration levels as a function of incubation time. The uncertainty is averaged over all peptides available at a given time point in a selected state. This chart has a double function: firstly, it allows checking if the measurement uncertainty is decreasing over time (which is the expected behavior). Secondly, it helps to plan the appropriate incubation length for the tested protein (whether we obtain the desired data reliability values).
