- Data Structures to represent AminoAcids, Mass Table, etc.
- Functions to compute different Properties such as isoelectric point, retention time, sequence length and masses.
- Reference table of the main Ontology terms used in PRIDE-toolsuite.
- General functionalities and data structures classes missing in JDK, such as: Tuple.
- General functionalities like checking email format and availability.
- mol: contains classes describing entities at the molecular level, such as: amino acids, neutrual losses, peptides and fragment ions.
- gui: contains several GUI components, you can use them if you want to replicate some of the features in PRIDE Inspector.
- data: contains data structures classes are missing from JDK, such as: Tuple.
- util: contains a selection of convenient classes. For examples: for formatting protein related informations, for checking Internet availability or for verify email addresses.
Note: the library is still evolving, we are committed to expand this library and add more useful classes.
The zip file in the releases section contains the PRIDE Utilities jar file and all other required libraries.

Here we will show you how to use the PRIDE Utilities library to calculate m/z delta and calculate theoretical mass of a given peptide.
You can find the method for calculating m/z delta from MoleculeUtilities in uk.ac.ebi.pride.mol package. It requires four input parameters:
/*
* sequence is the peptide sequence in String,
* precursorMz is the precusor m/z in double,
* precursorCharge is the precursor charge in double,
*ptmMasses is a list of post translational modifications in double.
*/
// Direct call on the method
Double mzDelta = MolecularUtilitites.calculateDeltaMz(sequence, precursorMz, precursorCharge, ptmMasses);You can also find the method for calculating theoretical mass value from MoleculeUtilities. It needs two input parameters:
/*
*sequence is the peptide sequence in String,
*masses is a optional list array of masses you want to add as extras.
The following lines of code shows you how:
*/
// Direct call on the method
double result = MolecularUtilitites.calculateTheoreticalMass(sequence, masses);
// Tip: Take a close look at other methods within MoleculeUtilitites, you might find them useful.
