⁠KnowEnG's General Clustering Pipeline

This is the Knowledge Engine for Genomics (KnowEnG), an NIH BD2K Center of Excellence, General Clustering Pipeline.

This pipeline clusters a spreadsheet's columns, with various methods:

Options	Method	Parameters
K-means	K Means	kmeans
hierarchical clustering	hierarchical clustering	hclust
Linked hierarchical clustering	hierarchical clustering constraint	link_hclust
Bootstrapped hierarchical clustering	consensus hierarchical clustering	cc_ hclust
Bootstrapped K-means	consensus K Means	cc_kmeans
Bootstrapped Linked hierarchical clustering	consensus linked hierarchical clustering	cc_link_hclust

⁠How to run this pipeline with Our data

⁠1. Clone the General_Clustering_Pipeline Repo

 git clone https://github.com/KnowEnG-Research/General_Clustering_Pipeline.git

⁠2. Install the following, for Linux

 apt-get install -y python3-pip libfreetype6-dev libxft-dev libblas-dev liblapack-dev libatlas-base-dev gfortran
 pip3 install pyyaml knpackage scipy==0.19.1 numpy==1.11.1 pandas==0.18.1 matplotlib==1.4.2 scikit-learn==0.17.1

⁠3. Change directory to General_Clustering_Pipeline

cd General_Clustering_Pipeline

⁠4. Change directory to test

cd test

⁠5. Create a local directory "run_dir" and place all the run files in it

make env_setup

⁠6. Use one of the following "make" commands to select and run a clustering option:

Command	Option
make run_kmeans_binary	Clustering with k-means
make run_kmeans_continuous
make run_hclust_binary	Hierarchical Clustering
make run_hclust_continuous
make run_link_hclust_binary	Hierarchical linkage Clustering
make run_link_hclust_continuous
make run_cc_kmeans_binary	Consensus Clustering with k-means
make run_cc_kmeans_continuous
make run_cc_hclust_binary	Consensus Hierarchical Clustering
make run_cc_hclust_continuous
make run_cc_link_hclust_binary	Consensus Hierarchical linkage Clustering

⁠How to run this pipeline with Your data

Follow steps 1-5 above then do the following:

⁠* Create your run directory

mkdir run_dir

⁠* Change directory to the run directory

cd run_dir

⁠* Create your results directory

mkdir results

⁠* Create run_paramters file (YAML Format)

Look for examples of run_parameters in the General_Clustering_Pipeline/data/run_files zTEMPLATE_cc_hclust.yml

⁠* Modify run_paramters file (YAML Format)

Change processing_method to one of: serial, parallel depending on your machine.

processing_method: serial

set the data file targets to the files you want to run, and the parameters as appropriate for your data.

⁠* Run the General Clustering Pipeline:

Update PYTHONPATH enviroment variable

export PYTHONPATH='../':$PYTHONPATH

python3 -m kngeneralclustering.general_clustering -run_directory ./run_dir -run_file zTEMPLATE_cc_net_nmf.yml

⁠Description of Output files saved in results directory

Output files of all methods save row by col heatmap variances per row with name row_variance_{method}_{timestamp}_viz.tsv.

	variance
row 1	float
...	...
row m	float

Output files of all the methods save row by col heatmap with name row_by_col_heatmp_{method}_{timestamp}_viz.tsv.

	col 1	...	col n
row 1	float	...	float
...	...	...	...
row m	float	...	float

Output files of all methods save col to cluster map with name col_labeled_by_cluster_{method}_{timestamp}_viz.tsv.

	cluster
col 1	int
...	...
col n	int

Output files of all methods save row scores by cluster with name row_averages_by_cluster_{method}_{timestamp}_viz.tsv.

	cluster 1	...	cluster k
row 1	float	...	float
...	...	...	...
row m	float	...	float

Output files of all methods save spreadsheet with top ranked rows per column with name top_row_by_cluster_{method}_{timestamp}_download.tsv.

	cluster 1	...	cluster k
row 1	1/0	...	1/0
...	...	...	...
row m	1/0	...	1/0

All methods save three silhouette scores: silhouette overall score, silhouette per cluster score and silhouette per sample with name silhouette_{method}_{timestamp}_viz.tsv.
1. silhouette overall score file: | number of clusters | silhouette score |
2. silhouette per cluster score file: | ith clusters | corresponding silhouette score |
3. silhouette per sample score file: | ith sample | corresponding silhouette score|
