Welcome to HCBC Platform

Welcome to our Platform guidelines web-page. Here analysts and developers will find guidelines on how to work with our most common environments.

We are developing platforms for each analysis type we have experience with at HCBC. Currently we fully support:

  • bulk RNAseq analysis

Go to each analysis-type section to learn how to use our platform.

Set up the package

  • Using O2 open OnDemand:

    • Remove bcbio from you PATH by commenting the line in your .bashrc if you have it
    • Start Rstudio with these modules on: gcc/9.2.0 imageMagick/7.1.0 geos/3.10.2 cmake/3.22.2 R/4.3.1 fftw/3.3.10 gdal/3.1.4 udunits/2.2.28 boost/1.75.0
    • Add --exclude=compute-f-17-[09-25] to the 'Slurm Custom Arguments' field
    • When the session is started, set you library path typing this command in your console Rstudio window: .libPaths("/n/app/bcbio/R4.3.1_rnaseq")

  • Load bcbioR with library(bcbioR)

  • Make sure the version is 0.1.3 with this command packageVersion("bcbioR") or re-install with devtools::install_github("bcbio/bcbioR",build_manual = TRUE, build_vignettes = TRUE), if you are in your own environment

General Project

Use the hcbc app to set up projects names. This name will be used for O2/FAS/github and dropbox. They may be already defined in the Trello card.

This set up needs bcbioR and usethis packages.

Make sure the version is 0.1.3 with this command packageVersion("bcbioR") or re-install with devtools::install_github("bcbio/bcbioR",build_manual = TRUE, build_vignettes = TRUE), if you are in your own environment

  • Create an R Project located in your project folder: usethis::proj_activate("/path/to/analysis/folder")
  • Deploy folders/files compatible with any project: bcbioR::bcbio_templates(type="base", outpath="/path/to/analysis/folder")
  • Start a git repository: usethis::use_git()

If you want to push this project to GitHub, follow these steps:

  • Only once every 30 days, set up your github credentials: usethis::gh_token_help()
  • NOTE You may want to run this first to keep this token working in future sessions in O2/FAS: git config --global credential.helper store
  • Push repository to HBC github as private: usethis::use_github(org="hbc",private=TRUE)

RNAseq

Use this common library path to perform your analysis: .libPaths("/n/app/bcbio/R4.3.1_rnaseq"). * Follow the previous step to set up the base project * Follow this instruction https://bcbio.github.io/bcbioR/#set-rnaseq-report-folder to start your RNAseq analysis

scRNAseq

Please, change to this common library path to perform your analysis: .libPaths("/n/app/bcbio/R4.3.1_singlecell").

ChipSeq

Please, change to this common library path to perform your analysis: .libPaths("/n/app/bcbio/R4.3.1_chipseq").

bcbioR supported templates

We used bcbioR to deploy folders and code to our project directories to improve robustness in our analysis.

You can install bcbioR as indicated here: https://github.com/bcbio/bcbioR/tree/main

  • RNAseq
  • CELLCHAT TEASeq
  • COSMX
  • scRNAseq

These materials have been developed by members of the teaching and platform team at the Harvard Chan Bioinformatics Core (HBC) RRID:SCR_025373.
