OligoArray development

  • writing new batch processing functions to run OligoArray with sbatch on Odyssey.
  • encorporating new functions into matlab-functions.
  • Pulled matlab-storm, matlab-functions, and storm-analysis repositories into my remote folder on Odyssey /n/home05/boettiger/
  • debugging remote OligoArray launcher. A bit cumbersome editing in local repository and push/pulling through github.

New Odyssey commands

  • to cancel / kill processes:
  • scancel jobid – kill job number jobid
  • scancel -t PENDING kill all pending jobs

Project 2

Chromatin project

STORM imaging

  • O/N run completed successfully, but 405 laser was off. Hence insufficient swithcing.
  • Examining 750 samples
    • G3-p4 750 staining evident in every cell (though weak / low contrast high background). Maybe just need less secondary, I know this primary alone looks good. Oddly the G2-p1 647 looks worse than usual.
    • 750 staining not that detectable in G08-p3 sample. Background high. G06-p1 staining does not look nearly as good as in previous stains. Maybe I should go and re-image those G06s soon, I think the only data I currently have from G06 missed the RNase digestion.

Data Analysis

  • ChromatinCropper of C02 data. Data is pretty noisy, I suspect bad switching contributes. may want to restain and reimage.
  • analyzed through image 18 (30+ loci)
  • analyzed E01 data from truncated STORM1 run. Actually pretty decent switching
  • analyzing E01 data moved to STORM2. Should have replaced buffer — spots look fantastic but sparsely sampled. Not enough switching. Movies much to short as well compared to expected length for a 250kb (yellow) region. Should get ~125+ frames of good switching for a region of this size.

single color to stain and image

  • C02 (rpt)
  • C08 (rpt)
  • E04
  • E05
