Germán,
Excellent obse4rvaton of the data!

Hi. I sent an email to Dex and Claire about this.
Technically, we are not reporting codon or anti-codon but rather the DNA sequence that makes the anti-codon. So I can see why this gets confusing.

Evan,
GeneMark does call all starts ATG, GTG, and TTG (you will find that GenMark can agree with Glimmer on a TTG start in DNA Master). However, GeneMrk's graphic output is only coded to represent ATG (longer upticks) and TTG (shorter upticks) starts. I think they ran out of money to update all of the graphic displays…..

Check out the genes upstream of the tail assembly chaperone (in Adaia, they are genes 8 and 9). it is easy to see that gene 8 is the major tail (HHPred results). Remember that it matches the SPP1 crystal structure project. This gene matches "H" which is a major tail protein and NOT the portal or head-to-tail connector complex protein. I am wondering if there is a legitimate programmed frameshift with this protein. See Baranov, et al 2006 where a major tail +1 ribosomal slippage is cited in a Listeria phage, PSA. While our slippery sequence doesn't match the one found in that major tail protein, our major tail protein - gp 8 - is 140 amino acids, while gp9 is 130 amino acids. A quick look at other major tail proteins across the actinobacteriophages, I have found gp sizes of 170 - 282 amino acids. Just wondering if the major tail protein is in 2 genes in this case. Further review is needed.

Be careful as you look for the second part of the tail assembly chaperone (T protein). It is a tiny bit of coding potential directly upstream of the tape measure that is not always called (only 1 in 3 have predicted it so far). All of them have same slippery sequence. refer to genome annotations of Adaia, Sputnik, and Atraxa for the exact calls.

So you may be missing a driver. I am not sure. I have attached a picture of 3 files that should be in your DNA Master folder. Check the root of where these files are (captured in the attached photo) along with the 3 files that should be there. They are Windows files and don't move easily. I am providing one of them becuase it is the one that is usually missing. If you can't access this file from my DropBox, download it from the web.

The version is at help -> about.
If you have not changed preferences to use secure servers, you will not get blast results.
I have attached a picture of the correct settings.

Rick,
This post should get your DNA master updated.

New as of November 15, 2016

Some very important changes have been made to DNA Master to accommodate NCBI's new secure https protocols. Versions of DNA Master from before this date will not be able to connect to NCBI and thus will not be able to auto-annotate genomes or run BLAST.

Updating your DNA Master will allow you to be able to use NCBI's new protocols. See this blog post for more information.

I think that the functional call for this particular instance could be nuclease.

I think that we have missed a gene in these genomes. Look at the gap between upstream of the tape measure. I don't (yet) see the slippery sequence, but I think that is the T region of the G-T protein of a tail assembly chaperone.
