# APL
`APL` is a package developed for computation of Association Plots, a method for visualization and analysis of single cell transcriptomics data. The main focus of `APL` is the identification of genes characteristic for individual clusters of cells from input data.
When working with `APL` package please cite:
```
Gralinska, E., Kohl, C., Fadakar, B. S., & Vingron, M. (2022).
Visualizing Cluster-specific Genes from Single-cell Transcriptomics Data Using Association Plots.
Journal of Molecular Biology, 434(11), 167525.
```
## Installation
The `APL` can be installed from GitHub:
library(devtools)
install_github("VingronLab/APL")
To additionally build the package vignette, run instead:
install_github("VingronLab/APL", build_vignettes = TRUE, dependencies = TRUE)
Building the vignette will however take considerable time.
**The vignette can also be found under the link: https://vingronlab.github.io/APL/ (hyperlink in the GitHub repository description).**
To install the `APL` from Bioconductor, run:
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("APL")
## Pytorch installation
In order to speed up the singular value decomposition, we highly recommend the installation of `pytorch`.
Users can instead also opt to use the slower R native SVD. For this, please set the argument `python = FALSE` wherever applicable in the package vignette.
### Install pytorch with reticulate
library(reticulate)
install_miniconda()
conda_install(envname = "r-reticulate", packages = "numpy")
conda_install(envname = "r-reticulate", packages = "pytorch")
### Manually install pytorch with conda
Download the appropriate Miniconda installer for your system from [the conda website](https://docs.conda.io/en/latest/miniconda.html).
Follow the installation instructions on their website and make sure the R package `reticulate` is also installed before proceeding.
Once installed, list all available conda environments via <br>
`conda info --envs` <br>
One of the environments should have `r-reticulate` in its name. Depending on where
you installed it and your system, the exact path might be different.
Activate the environment and install pytorch into it.
conda activate ~/.local/share/r-miniconda/envs/r-reticulate # change path accordingly.
conda install numpy
conda install pytorch
## Feature overview
Please run
vignette("APL")
after installation with `build_vignettes = TRUE` for an introduction into the package.
