Iain,
Refer back to the installation guide https://phagesdb.org/DNAMaster/ and see if the Chromo Book has the right specs. I am guessing that it does not. But check and see!
Best,

Hi all,
the most likely reason that you are not updating is that you are not running as an administrator. If IT is doing it, they will have privilege. If you are doing it, DON'T install in Program files, instead install elsewhere, like the desktop. Right click on the program, run as administrator to complete the update.

Kristen and Liz,
Not that I am aware. The latest cohort just installed for the December workshop. Updating, as long as the preferences were set correctly, was not an issue.

Cool paper about the tRNA expressed in the prophage (Fionnbharth) in M. smegmatis mc2. 155.
https://journals.asm.org/doi/10.1128/mbio.03260-23
It is a VERY atypical bench determined expression of a tRNA.

I would pick the latter, so the slippage is annotated as 10569-11030, 11030-11464. This slippage matches the programmed frameshift of phage Lambda, which is the phage where the slippage was experimentally determined. https://pubmed.ncbi.nlm.nih.gov/8230192/

Christine,
With no experimental evidence, it is difficult to say which it is, but it is thought that the +1 frameshift is far more common than the -2. So that is what I would annotate.
There are a lot of unannotated frameshifts in this subcluster, mostly becsuse we made a decision to only annotate those sequences found in the literature. (See the guide for the list). However, this sequence is so well conserved, i think it can be called.

Terrific! You can do this!

Hi Colleen,
The simplest answer is that you are not propagating A. globi any longer.
Do you have your original stock material? It is time to revert to that!

A good practice is that all cultures be subbed from the parental strain, an F1 or F2 generation is fine, but going beyond that is problematic.

Best,

Hi Colleen,
Does the control phage provide show no plaques also?
