Hi Nancy, I used the posted file and was able to auto-annotate. Were other students able to annotate. sounds like something is up with the student's installation of DNA Master, or their Windows is interpreting the file as something it is not. debbie |

Hi Nancy, Let's see if I can help. But I need more information. Are you in DNA Master, file -> open -> FastA multiple sequence file? Is the file the .fasta file for your phagesDB phage page. Is it a text file? Can you open a different dna master file and navigate around it. Have you tried more than 1 different fasta file? debbie |

Adam, What do you want to call here? What is your evidence? debbie |

Adam, In the paper referred to the Bioinformatics Guide, the TAC 'template' is X_XX.Y_YY.Z. You have not provided enough information for me to look quickly, but check the guide to interpret the '_ 'and '.'s If your CCCTTTT lines up correctly for a -1 Frameshift, you have a canonical programmed ribosomal slippage. You also used an abbreviation 'PF' that i don't recognize. debbie |

Holly, Sorry for the confusion. The only program to use is DeepTMHMM. And only 1 transmembrane protein needs to be found to call a membrane protein. take care to interpret DeepTMHMM hits because some will identify signal proteins. At this time, we are not calling signal proteins. The Bioinformatics Guide is updated. debbie |

Hi all, If you are looking how to instal PDM utils on a M1 mac, you can follow this: On a series of MacBook Pro computers, including most recently an M1 mac, I have only ever done native installs of pdm_utils. The hardest part for me is MySQL – use an installer for 8.0.18 or later (earlier versions had funky bugs related to cascaded deletes!). Choose “Legacy Password” when prompted, and you’ll be forced to choose an 8-character or longer password (no more ‘phage’). Make sure you add mysql to the $PATH (export PATH=’/usr/local/mysql/bin:$PATH’) in your ~/.zshrc file. Other than that, if you use some flavor of conda to manage the third-party dependencies (Aragorn, trnascan-se, mmseqs2, blast) pdm_utils should be just fine. –Christian Gauthier |

Hi Adam, I know very little about Streptomyces phages annotations. When I first looked at this, I most wanted to respect coding potential. Tonight, I had to ask - after your most recent questions - how many BD phages are there. Looks like there are 43 members in BD, with 11 in subcluster BD2. And additional phages in the rest of the BD subcluster. My impression is that the right arms of BD phages are filled with small genes and lots of HGT. Because of the overlap, I expected to see lots of hits to the c terminus of this overlapping gene. But if you blastn 44271- 43849, you can see what this looks like athere are 2 genes in the region. My take, with the short amount of time I have looked at this, is that there is no clear answer here. If you choose the longer overlap, please be sure to include your justification when you submit. There is definitely more digging to do. And no, this won't get answered until you look at all the data, don't leave out the functional investigation as you continue to consider this. debbie |

Hi all, For the past week or so the tRNA Aragorn site is not responding. We are investigating. I'll keep you posted. debbie Feb. 13, 2024 Argorn is back up at a new location The new site is running Aragorn 1.2.41 and can be found here. http://www.trna.se/ARAGORN/ |

Adam, Next time, please use coordinates. I just looked too quickly, my apologies. I would call the big overlap. This is a great opportunity to imagine how a toxin/antitoxin pair would work. and that is saying that i am not sure it is even a toxin/antitoxin pair. Another key point, you aren't done with your positional annotation until you have looked at the functional annotation. You can convince yourself that the gene and the start are the right calls, but investigating the functional call may show you you are wrong because you are missing a needed domain or the opposite - there is no functional information the helps. As for the picture that you sent, the dissimilar nucleotide sequence in the bottom genome negates inferring anything about what genes to call in your genome without further inspections. do you use the multiple protein seqeuece alignments from phagesDB/phamerator? In this case, you may want to call a toxin, but can you identify an anti-toxin? so many good questions! debbie |

Hi Adam, This is not a gap-filling exercise. There is great coding potential. If I am at the correct gene (you didn't provide coordinates), there is a 31 base overlap between the gene that starts at 44145 and the next one that ends at 44114. Not that troublesome in this context. Just as important is that there are interesting hits to the gene that ends at 44114. More investigation is needed but I would want to know if I can make a 'toxin' or a DNA binding functional assignment. |
