(2022). _[SIMSI-Transfer: Software-assisted reduction of missing values in phosphoproteomic and proteomic isobaric labeling data using tandem mass spectrum clustering.](https://www.sciencedirect.com/science/article/pii/S1535947622000469)_ Molecular & Cellular Proteomics, 100238.
## Test dataset
For testing SIMSI-Transfer after installation, we recommend downloading the TMT11 MS2 raw files from this publication:
Thompson, A., Wölmer, N., Koncarevic, S., Selzer, S. et al., _[TMTpro: Design, Synthesis, and Initial Evaluation of a Proline-Based Isobaric 16-Plex Tandem Mass Tag Reagent Set.](https://pubs.acs.org/doi/abs/10.1021/acs.analchem.9b04474)_ Analytical Chemistry 2019, 91, 15941–15950. doi:10.1021/acs.analchem.9b04474
PRIDE link: https://www.ebi.ac.uk/pride/archive/projects/PXD014750
Raw files for TMT-MS2:
- 19070-001.raw
- 19070-002.raw
- 19070-003.raw
- 19070-006.raw
- 19070-007.raw
- 19070-008.raw
The MaxQuant results needed as input to SIMSI-Transfer can be downloaded from Zenodo:
- [10.5281/zenodo.6365902](https://zenodo.org/record/6365902)
For reference, the original SIMSI-Transfer results (v0.1.0) for this dataset can also be downloaded from Zenodo:
- [10.5281/zenodo.6365638](https://zenodo.org/record/6365638)
## Running SIMSI-Transfer using the GUI
On Windows, you can download the `SIMSI-Transfer_GUI_windows.zip` from the latest release, unzip it and open `SIMSI-Transfer.exe` to start the GUI (no installation necessary).
Alternatively, on all platforms, first install SIMSI-Transfer as explained below. Then install `PyQt5` (`pip install PyQt5`) and run:
```shell
python gui.py
```
## Running SIMSI-Transfer from the command line
First install SIMSI-Transfer **as explained below**, then run SIMSI-Transfer:
```shell
python -m simsi_transfer --mq_txt_folder </path/to/txt/folder> --raw_folder </path/to/raw/folder> --output_folder </path/to/output/folder>
```
Alternative command for MS3 acquisition, using the TMT correction factor file exported from MaxQuant:
```shell
python -m simsi_transfer --mq_txt_folder </path/to/txt/folder> --raw_folder </path/to/raw/folder> --output_folder </path/to/output/folder> --tmt_ms_level ms3 --tmt_requantify --tmt_reporter_correction_file </path/to/correction/factor/file.txt>
```
Alternative command using the meta input file for MS3 acquisition, with filtered decoys:
```shell
python -m simsi_transfer --meta_input_file </path/to/meta/file> --output_folder </path/to/output/folder> --tmt_ms_level ms3 --tmt_requantify --filter_decoys
```
A list of all possible arguments is displayed using the help argument:
```shell
python -m simsi_transfer --help
```
## Installation
SIMSI-Transfer is available on PyPI and can be installed with `pip`:
```shell
pip install simsi-transfer
```
Alternatively, you can install SIMSI-Transfer after cloning from this repository:
```shell
git clone https://github.com/kusterlab/SIMSI-Transfer.git
pip install .
```
