# PROSPECT PTMs - Fragment Ion Intensity Prediction (MS2)
A mass-spectrometry dataset for applied machine learning in proteomics, annotated, processed and split for the task of fragment ion intensity prediction.
## Dataset Details
- **Curated by:** Wilhelmlab - Technical University of Munich - School of Life Sciences - Germany
- **License:** CC-BY4.0
### Dataset Sources
The data is based on the PROSPECT PTMs datasets hosted in Zenodo [3][4][5][6].
- **Repository:** https://github.com/wilhelm-lab/PROSPECT
## Uses
The dataset is intended to be used for fragment ion intensity prediction given a peptide sequence. Optionally, addiional inputs can be used as features to encode PTMs or other features describing the experimental setup.
## Dataset Structure
The dataset has two configurations:
- default: this is the train/val/test data that is based on all the Zenodo PROSPECT PTMs datasets [3][4][5]
- holdout: this is the holdout datasets that can be eventually used to evaluate a model capable of processing PTMs. It is based on the PROSPECT Test-PTM dataset on Zenodo [6].
Use one of the following lines to load the respective configuration:
```python
# main data for training and evaluation; contains train, val, tesst splits
main_dataset = load_dataset("Wilhelmlab/prospect-ptms-ms2")
# holdout data for final benchmarking and model comparison; contains test split only
holdout_dataset = load_dataset("Wilhelmlab/prospect-ptms-ms2", "holdout")
```
## Dataset Creation
### Curation Rationale
The dataset is intended to serve as a reference benchmark dataset for fragment ion intensity prediction, processed, split, and ready-to-use for developing deep learning models for this specific task.
### Source Data
The upstream source data is based on the ProteomeTools datasets available on PRIDE [1][2].
#### Data Collection and Processing
[More Information Needed]
### Annotations
The annotations are based on an expert system [7] with a set of rules listed in the PROSPECT paper [8]. The vector of intensities is collected in one column named `intensities_raw`.
#### Personal and Sensitive Information
The dataset does not contain any personal, sensitive, or private data.
### Recommendations
We recommend using the holdout configuration for solely evaluation models at the end of the research iteration.
