Interactive Analysis (Notebooks)

New images!

  • Updated all python-derived Terra images to compile pysam with Google Cloud support. This allows pysam to access GCS objects directly without having to first localize to the runtime.

  • Refactor around CRAN and Bioconductor system dependencies for all images that have R dependency (terra-docker-r, terra-docker-gatk, terra-docker-bioconductor)

Workflows, Google integrations and UI

This release includes back-end updates to workflows, Google integrations, and the UI, to improve upcoming features.

    This article states "Updated all python-derived Terra images to compile pysam with Google Cloud support. This allows pysam to access GCS objects directly without having to first localize to the runtime" — can you clarify exactly how this is supposed to work? Simply trying:

    samfile = pysam.AlignmentFile("gs://bucket/mybam.bam", "rb")

    results in:

    Failed to open file "gs://bucket/mybam.bam" : Permission denied

    Resurrecting a dead thread to say that adding this before the call to pysam.AlignmentFile() worked for me:

     

    import os, subprocess
    os.environ['GCS_OAUTH_TOKEN'] = subprocess.check_output('gcloud auth application-default print-access-token', shell=True).decode().strip()
