  • CIRCLET
  • CIRCLET
    CIRCLET, a powerful tool for accurate reconstruction of circular trajectory with high resolution by considering multi-scale features of chromosomal architectures of single cells. Further division of the reconstructed trajectory helps to accurately characterize the dynamics of chromosomal structures and uncover important regulatory genes along cell-cycle progression, providing a novel framework for discovering regulatory regions even cancer markers at single-cell resolution. [Guide]
  • PBLR
  • PBLR
    Single-cell RNA sequencing (scRNA-seq) data analysis remains challenging due to the presence of dropout events (i.e., excess zero counts). Taking account of cell heterogeneity and expression effect on dropout, we propose PBLR to accurately impute the dropouts of scRNA-seq data. PBLR is an effective tool to recover dropout events on both simulated and real datasets,and can dramatically improve low-dimensional representation and reveal gene-gene relationship compared to several state-of-the-art methods.
  • MSTD
  • MSTD
    MSTD is a generic and efficient method to identify multi-scale topological domains (MSTD) from symmetric Hi-C and other high resolution asymmetric promoter capture Hi-C datasets. [Guide]
  • gkm-DNN
  • gkm-DNN
    gkm-DNN (gapped k-mer deep neural network) is a software which uses gapped k-mer frequency vector (gkm-fv) as input to train neural networks. gkm-DNN is designed for classification but can be easily extended to other problems such as regression and ranking. The software is open sourced. gkm-DNN consists of calculating gkm-fv (using R) and training the neural networks (using Java + DL4J). For more information please see user guide. [Guide]
  • MIA
  • MIA
    MIA (Matrix Integration Analysis) is a MATLAB package, implementing and extending four computational methods (Guide). MIA can integrate diverse types of genomic data (e.g., copy number variation, DNA methylation, gene expression, microRNA expression profiles and/or gene network data) to identify the underlying modular patterns. MIA is flexible and can handle a wide range of biological problems and data types. In addition, MIA can also be run for users without a MATLAB license. [Guide]
  • MDPFinder
  • MDPFinder
    MDPFinder (Mutated Driver Pathway Finder) is a package for identifying driver pathways promoting cancer proliferation and filtering out the unfunctional and passenger ones. It includes two methods to solve the so-called Maximum Weight Submatrix problem which is designed to de novo identify mutated driver pathways from mutation data in cancer. The first one is an exact method which can be helpful for assessing other approximate or/and heuristic algorithms. The second one is a stochastic and flexible method which can be employed to incorporate other types of information to improve the first method.   [Pubmed]
  • CoMDP
  • CoMDP
    CoMDP (Co-occurring Mutated Driver Pathway) is a package for de novo identifying co-occurring driver pathways in cancer with mutation data. The modified version mod_CoMDP can be used to model the situation where a certain pathway has been previously proven to play important roles in some cancers and one wants to know whether there are other pathways with cooperative effects with it.   [Pubmed]
  • dCMA
  • dCMA
    dCMA (differential Chromatin Modification Analysis) is a package for identifying cell-type specific genomic regions with distinctive chromatin modifications. It can find cell-type specific elements which are unique to a cell type investigated. This differential comparative epigenomic strategy is a promising tool in deciphering the human genome and characterizing cell specificity.   [Pubmed]
  • jNMF
  • jNMF
    jNMF is a package which implemented the joint matrix factorization technique to integrating multi-dimensional genomics data for the discovery of combinatorial patterns. It projects multiple types of genomic data onto a common coordinate system, in which heterogeneous variables weighted highly in the same projected direction form a multi-dimensional module (md-module). Genomic variables in such modules are characterized by significant correlations and likely functional associations.   [Pubmed]
  • sMBPLS
  • sMBPLS
    sMBPLS (sparse Multi-Block Partial Least Squares) is a package to identify multi-dimensional regulatory modules from multiple datasets in a regression manner. A multi-dimensional regulatory module contains sets of regulatory factors from different layers that are likely to jointly contribute to a local "gene expression factory".   [Pubmed]
  • SNPLS
  • SNPLS
    SNPLS (Sparse Network-regularized Partial Least Squares) is a package to integrate pairwise gene expression and drug response data as well as a gene interaction network for identifying joint gene-drug co-modules in a regression manner. This package can be easily adapted to other biological pairwise data.   [Pubmed]
  • HTTMM
  • HTTMM
    HTTMM (Hierarchical Taxonomy Tree based Mixture Model) is a package designed for estimating the abundance of taxon within a microbial community by incorporating the structure of the taxonomy tree. In this model, genome specific short reads and homologous short reads among genomes can be distinguished and represented by leaf and intermediate nodes in the taxonomy tree respectively. An expectation- maximization algorithm has been adopted to solve this model.   [Pubmed]
  • NSLR
  • NSLR
    NSLR (Network-regularized Sparse Logistic Regression) is a package to integrate gene expression data, clinical binary outcome, and normalized Laplacian matrix encoding the protein-protein interaction (PPI) network for clinical risk prediction and biomarker discovery. [Guide]
  • ESPCA
  • NSLR
    ESPCA (Edge-group Sparse PCA) is a package to integrate the group structure from a prior gene network into the PCA framework for dimension reduction and feature interpretation. ESPCA enforces sparsity of principal component (PC) loadings through considering the connectivity of gene variables in the prior network. Based on such prior knowledge, ESPCA can overcome the drawbacks of sparse PCA and capture some gene modules with better biological interpretations. We also extended ESPCA for analyzing multiple gene expression matrices simultaneously. [Guide]
  • JMF
  • NSLR
    JMF (Joint Matrix Factorization) is a MATLAB package to integrate multi-view data as well as prior relationship knowledge within or between multi-view data for pattern recognition and data mining. Four update rules are adopted for solving JMF. Additionally, two adapted prediction JMF models based on JMF are provided. [Guide]
  • CSMF
  • CSMF
    CSMF (Common and Specific Matrix Factorization) is a MATLAB package to simultaneously extract common and specific patterns from the data of two or multiple biological interrelated conditions via matrix factorization. In addition to the main functions, this package also includes data simulation, parameter selection, solution fine tuning, etc. CSMF can be widely used to analyze various data types such as RNA-seq, Chip-seq and scRNA-seq.
