New to R, but enthusiastic to start easing into the world of bioinformatics analysis. Currently partway through my PhD, creating and testing new protocols (ChIP-Seq, bioinformatics analyses) solo in a small research group without an expert or experienced Post-Doc/PI to provide guidance.

I've read through the DiffBind Vignette a few dozen times, and followed through a video tutorial hosted on the Cancer Research UK site a half dozen more, worked through dozens of pretty niave error codes to get here. I'm still learning so thanks for your patients.

I keep running into this error code now that I've walked through using DiffBind in R Studio with a practise sample sheet (with only a few samples versus all my samples for ease of use and ease of troubleshooting). Example samplesheet run did not have this problem.

With my full sample sheet created and read into RStudio, I keep getting the following error right at the beginning of the analysis.

Troubleshooting so far has included:

  • checking paths in R to confirm files exist and haven't been pulled into iCloud (using mac laptop).
  • checking all .bam files have data/aren't empty, everything seems to be fine.
  • checking that R is up to date, and current version of Bioconductor/BiocManager/DiffBind are being used.

In my limited experience, I can't conceptualize what's going wrong. To the best of my investigative skills, the information on BioStars or this Bioconductor Help site have been limited related to this specific error code.

Thanks in advance for time and help!

I see the PeakCaller is set to macs, are your peak files the .xls files generated by MACS?

If they are, it would help to see your sample sheet and at least one (preferably all) of the peak files (you can email to me if you want).
