naivestates - Inference of cell states using Naive Bayes
This work is supported by the NIH Grant 1U54CA225088: Systems Pharmacology of Therapeutic and Adverse Responses to Immune Checkpoint and Small Molecule Drugs and by the NCI grant 1U2CCA233262: Pre-cancer atlases of cutaneous and hematologic origin (PATCH Center).

Introduction
naivestates is a label-free, cluster-free tool for inferring cell types from quantified marker expression data, based on known marker <-> cell type associations. The tool is designed to be run as a Docker container, but can also be installed in a Conda environment or as an R package. naivestates expects as input information about marker expression on a per-cell basis, provided in .csv format. One of the columns must contain cell IDs. An example input file may look as follows:

CellID,KERATIN,FOXP3,SMA
1,64.18060200668896,193.00334448160535,303.5016722408027

Installation
Download the container image
Pull the latest version with

docker pull labsyspharm/naivestates
Alternatively, you can pull a specific version, which is recommended to ensure reproducibility of your analyses. For example, v1.2.0 can be pulled with

docker pull labsyspharm/naivestates:1.2.0
Examine the tool usage instructions
docker run --rm labsyspharm/naivestates:1.2.0 /app/main.R -h
replacing 1.2.0 with the version you are working with. Omit :1.2.0 entirely if you pulled the latest version above. The flag --rm tells Docker to delete the container instance after it finishes displaying the help message.

Basic usage
At minimum, the tool requires an input file and the list of marker names:

docker run --rm -v /path/to/data/folder:/data labsyspharm/naivestates:1.2.0 \
  /app/main.R -i /data/myfile.csv -m aSMA,CD45,panCK
where we can make a distinction between Docker-level arguments:

--rm once again cleans up the container instance after it finishes running the code
-v /path/to/data/folder:/data maps the local folder containing your data to /data inside the container
:1.2.0 specifies the container version that we pulled above
and tool-level arguments:

-i /data/myfile.csv specifies which data file to process
-m aSMA,CD45,panCK specifies the markers of interest (NOTE: comma-delimited, no spaces)
If there is a large number of markers, place their names in a standalone file markers.txt with one marker per line. Ensure that the file lives in /path/to/data/folder/ and modify the Docker call to use the new file:

docker run --rm -v /path/to/data/folder:/data labsyspharm/naivestates:1.2.0 \
  /app/main.R -i /data/myfile.csv -m /data/markers.txt
Additional parameters
The following parameters are optional, but may be useful in certain scenarios:

--plots <off|pdf|png> - (default: off) Produces QC plots of individual marker fits and summary UMAP plots in .png or .pdf format.
--id - (default: CellID) Name of the column that contains cell IDs
--log <yes|no|auto> - (default: auto) When a log10 transformation should be applied prior to fitting the data. The tool will do this automatically if it detects large values. Use --log no to force the use of original, non-transformed values instead.
-o - (default: /data) Alternative output directory. (Note that any file written to a directory that wasn't mapped with docker -v will not persist when the container is destroyed.)
--mct - The tool has a basic marker -> cell type (mct) mapping in typemap.csv. More sophisticated mct mappings can be defined by creating a custom-map.csv file with two columns: Marker and State. Ensure that custom-map.csv is in /path/to/data/folder and point the tool at it with --mct (e.g., /app/main.R -i /data/myfile.csv --mct /data/custom-map.csv -m aSMA,CD45,panCK)
Alternative execution environments
Running in a Conda environment
If you are working in a computational environment that doesn't support Docker, the repository provides a Conda-based alternative. Ensure that conda is installed on your system, then 1) clone this repository, 2) instantiate the conda environment and 3) install the tool.

git clone https://github.com/labsyspharm/naivestates.git
cd naivestates
conda env create -f conda.yml
conda activate naivestates
R -s -e "devtools::install_github('labsyspharm/naivestates')"
The tool can now be used as above by running main.R:

./main.R -h
./main.R -i /path/to/datafile.csv -m aSMA,CD45,panCK
Running as an R package
The tool can also be installed as an R package directly from GitHub:

if( !require(devtools) ) install.packages("devtools")
devtools::install_github( "labsyspharm/naivestates" )
Example usage:

library( tidyverse )
library( naivestates )

# Load the original data
X <- read_csv( "datafile.csv" )

# Fit models to channels aSMA, CD45 and panCK
# Specify that cell IDs are in column CellID
GMM <- GMMfit( X, CellID, aSMA, CD45, panCK )

# Plot a fit to one of the markers
plotFit( GMM, "CD45" )

# Write out the results to results.csv
GMMreshape(GMM) %>% write_csv( "results.csv" )
