and I just revised the protocol again. |

Chris, Blast x takes a nucleotide sequence, translates it into all 6 reading frames and blasts. That is not needed if you want to know if the thing that was predicted by Glimmer and GeneMark has any homologues. tBlastx takes too long and would just be confusing, coding potential provides you the ORF you want to zero in on. If at any time, you think you need to look elsewhere - in another reading frame- go for it. Using nucleotide sequences to look for function homologues is not nearly as helpful as using the protein sequence. The ORFs identified by Glimmer and GeneMark (and in your auto-annoted DNA Master file) have pushed past looking for protein homologues across all 6 reading frames and showing the most likely ORF with coding potential (those are powerful and proven algorithms. Blastx of any kind is not routinely done. It can be used when you are just not convinced of what you are finding. Hope that helps, debbie |

Hi. I typically use the phage trained GeneMark in PECAAN, so no harm. Be sure to label the file so you know which one it is. BUT I use the host(s) trained outside of PECAAN because all can be informative, especially in the difficult to call areas. debbie |

Hi Greg, I am not having trouble blasting. (I only blasted 1 gene but it completed in less than 3 minutes. I would guess that this is a server/firewall sort of problem. I would recommend restarting your computer then calling your IT folks. debbie |

Hi Steve, https://seaphages.org/forums/topic/224/ This link will take you to PECAAN‘s user guide. It provides directions for you to add your phage to PECAAN. Thanks, debbie |

Maria, without evidence, Hypothetical Protein is the best choice. thanks, debbie |

Andrea, That is just incorrect. Gene 21 in ActinUp is the tape measure. debbie |

Hi all, And remember that Holliday is named after a person, so it is one of the few words that we capitalize. "In 1964, Robin Holliday proposed a model to explain three important events that occur during meiosis in fungi: crossing-over, gene conversion, and postmeiotic segregation." (Holliday Junction Resolvases,Cold Spring Harb Perspect Biol. 2014 Sep; 6(9): a023192. doi: 10.1101/cshperspect.a023192) |

Fernando, There are a lot of factors that impact how poorly Blast completes. It sounds like it just needs to have more time. I have waited longer than overnight to complete a blast. You can try blasting in sections. See this section of the guide. https://seaphagesbioinformatics.helpdocsonline.com/article-70 good luck! debbie |
