A multiplet removal tool for processing cell hashing data
Project description
# GMM-Demux A Gaussian Mixture Model based software for processing cell hashing data.
Blow shows an example classification result. Orange dots are multi-sample multiplets.

## Usage `bash python3 GMM-demux.py <cell_hashing_path> <HTO_names> <estimated_cell_num> ` MSM-free droplets are stored in folder GMM_Demux_mtx by default.
## Example Usage An example cell hashing data is provided in example_input. <HTO_names> can be obtained from the features.tsv file. `bash python3 GMM-demux.py example_input/outs/filtered_feature_bc_matrix HTO_1,HTO_2,HTO_3,HTO_4 35685 `
## Optional Arguments * -h: show help information. * -f FULL, –full FULL Generate the full classification report. Require a path argument. * -s SIMPLIFIED, –simplified SIMPLIFIED Generate the simplified classification report. Require a path argument. * -o OUTPUT, –output OUTPUT Specify the folder to store the result. Require a path argument. * -r REPORT, –report REPORT Specify the file to store summary report. Require a file argument.
## Output values * CellRanger MSM-free drops, in MTX format. Compatible with CellRanger 3.0.
## Online Cell Hashing Experiment Planner A GMM-Demux based online cell hashing experiment planner is publically accessible at [link](https://www.pitt.edu/~wec47/gmmdemux.html).
