DanRussell	Hi Heather, As long as everything is precisely typed into Phamerator, I think this is likely to be a Phamerator-Ubuntu issue rather than a PhamDB issue. Check out the suggestions in this post and see if any of those might help. Sometimes, weird stuff can happen on the VM which sends Phamerator into strange cycles, but Steve had a couple suggestions. https://seaphages.org/forums/topic/246/?page=1#post-1338 –Dan

DanRussell	grosej Hi Dan, I am wondering if there is a way to merge two PhamDB databases, such as by merging the mysql files? thanks! Julianne Grose Hi Juli, I don't know if you can merge two databases easily with PhamDB, but PhamDB definitely makes it easy to add phages that are in the system to other databases in the system without having to re-enter them. You can use the "Add to Database" function. –Dan

DanRussell	Hmmm…I was totally ready to say Chris is right, it's probably a 454 sequencing error, but here is the region in question in the assembly: The evidence for 6 Gs there is quite strong, and there are only a few reads that suggest only 5 Gs. That doesn't mean it's not truly 5 Gs, but I wouldn't feel comfortable changing the sequence on this evidence alone. I guess that means you should proceed as is? What do you think Welkin/Chris? –Dan

DanRussell	Summer Research Opportunity Next-generation Fluorescent Reporter Mycobacteriophages The Jacobs laboratory has innovative and multifaceted studies on the biology of Mycobacterium tuberculosis and its phages. We are seeking undergraduates who have taken the SEA-PHAGES course to work on an exciting project to generate next-generation fluorescent reporter mycobacteriophages. We have previously shown that fluorescent reporter mycobacteriophages can be used to rapidly assess drug susceptibilities of Mycobacterium tuberculosis cells in culture or directly from sputum samples (Jain et al., 2012 Journal of Clinical Micro. 50:1362-9). Recently, we have developed dual reporter mycobacteriophages that can be used to identify M. tuberculosis persister cells, a subpopulation of cells in a culture that are drug tolerant (Jain et al., 2016 mBio. 7 e01023-16). The summer program will focus on generating improved versions of reporter mycobacteriophages (greater sensitivity, shelf-life etc.). This experience will help students explore nuances of molecular biology and the scientific method. Students with a basic background in biology, recombinant DNA technology, and phage biology would be ideally suited for this project. The students will not need to work with virulent M. tuberculosis strains as we have developed Biosafety Level 2 strains for this project. The Jacobs Lab is located in the Price Translational Research Center at the Albert Einstein College of Medicine, 1301 Morris Park Avenue, Bronx, NY. Einstein is near the Bronx Zoo and the New York Botanical Gardens (both ideal phage hunting areas!). The position will come with an stipend of $11,000 for 3 months. If interested, please contact Dr. William R. Jacobs at jacobsw@hhmi.org Lab webpage: http://williamrjacobs.org

DanRussell	Hi Sangha, From looking at the DNA Master file, I think that the longer of these two (which overlaps a lot of other tRNAs) is just a miscall. You can safely delete that one. The 425 bp one, however, is probably a tmRNA, and should be called. –Dan

DanRussell	Shallee Page The last couple of days, I can't open the Lawrence Lab web page to download DNA master… Hi Shallee, This happens from time to time. Looks like the server has been reset and is working now. –Dan

DanRussell	Hi Nancy, These are probably tRNA genes, which don't appear in Phamerator (yet!). So for those you'll have to follow some of the tRNA guidelines rather than Starterator, Phamerator, etc. –Dan

DanRussell	Hi Victoria, If Phamerator ever prompts you for a password, it should just be: "phage". If that doesn't work, something else has gone wrong! –Dan

DanRussell	Hi Nikki, Glad it worked. Definitely shutting down the VM or closing your computer while Phamerator's running/doing things can cause problems. I'd always advise to close Phamerator before shutting anything else down. –Dan

DanRussell	Hi Nikki, Did you try "phage" for the password? If phamerator ever wants a password, that's the one. If that doesn't help, Steve recently answered a similar question via email, so I'm going to copy his response here: It sounds like one of two things: your virtual machine is unable to access the internet your phamerator configuration file has become corrupted You can test the first one by opening a browser in the virtual machine and trying to load any website. If that doesn’t work, you can usually solve the problem by rebooting the virtual machine or toggling the “enable networking” setting (turn off and then back on) from the dropdown menu near the top-right of your Ubuntu desktop. If that’s not the problem, I suggest that you move the Phamerator configuration file and allow Phamerator to recreate a default file: Steps to do this: Reboot the Virtual Machine Login as whichever account (seafaculty or seastudent) you prefer to use. (If you use both accounts, you will need to complete these steps logged in as each user.) Make sure Phamerator is NOT running. Open the terminal (click the Ubuntu “Dash” icon in the top-left corner, type “terminal” and hit the <enter> key) Paste in the following command: `mv ~/.phamerator/phamerator.conf ~/Desktop` Start Phamerator. You may need to update server to: http://phamerator.webfactional.com/databases_Hatfull and database to: Actino_Draft If prompted for a password, use: phage If everything appears to be in working order, you can delete the phamerator.conf file that is on your desktop. –Dan Edited 01 Mar, 2017 15:40
