cdshaffer	In DNA Master: 1. DNA Menu, bottom item is "Save ORF's…" which will bring up the tool window 2. You will see a list of all the features in your phage 3. Select one or more by clicking, or use the "Select all genes" button 4. Go to the "Specify Export Files" tab 5. Use the checkboxes as appropriate to control what will be saved (e.g. "Peptide Sequences" 6. Click the "Save" button

cdshaffer	Dan, Can you create a page that students can get to that has all the instructions for installing the machine just like on the protected /software/virtualmachine/ page? I would like to be able to point students to all those well written instruction on how to go about installing virtual machines once I give them the virtual disk I want them to use. thanks

cdshaffer	Well, I cannot say if we are getting "good" infections. We haven't tried to titer a stock with the different plating techniques. What I can say is every pair of students has a phage from their soil samples. So it seems to be working well enough.

We are using top agar with lividans and getting good plaques. Students are simply spreading phage solution on the plate, then adding top agar onto the plate with the spores already added to the top agar. Very Convenient, since it avoids the 15 min incubation step we did with phage + mycobacteria. Always nice in a class setting with limited time. So far so good for us, looks like we have at least a dozen phage isolated by direct plating. The hard part is growing and collecting the spores it adds time to prep work but they are expected to be stable throughout the phage isolation and purification stage so we only have to collect spores once.

cdshaffer	Dan, could you post the MD5 hash of the two images. I would like to confirm the integrity of the files after download. Thanks Chris

I tried TymAbreu_draft but that phage was not found, I have the most recent version of the Actino_draft database and in there the phage is no longer "_draft", its just Tymabreu. so I tested it out. Phage ran with no crashes, the likely culprit is confusion between the different "_draft" and current versions of the annotation. I suggest you use phamerator to update the actino_draft database and delete all the files in "Intermediate Files" folder (see the other "troubleshooting starterator" post) then try again. That is likely to work. However in case you need it, I posted the full phage report here. You can download from that link if the above suggestions fail to fix the problem on your system.

cdshaffer	more info on phage dori crash the last two genes in dori are problematic, for both of these genes there are no in-frame stop codons upstream of the annotated start codon all the way to the end of the phage. This appears to be causing the crashes. I am slowly working on how best to modify code with minimal risk of breaking something else. Edited 22 Jul, 2015 16:43

cdshaffer	phage Amela_Draft from the Actino_Draft database has also been reported to crash starterator.

OK I have that same error and stack trace for phage Dori pham 4536. Gene is the last gene and an orpham just ran snape got same crash, pham 26 of 100 ends up being pham 9858 and is also the last gene in the genome and is also an orpham. close inspection shows that this gene spans the ends and is annotated in DNA Master as going from 14 to 51601, however in phamerator the location is listed as just the part at the right end of the genome (i.e. 51601 to 52138 ). The predicted protein sequence is correct in phamerator database just not the right hand coordinate. This eventually leads to the crash. I can see in the code how this is handled for forward strand genes than span the end of the phage, but in these cases the coordinates are correct. Solution to handle this is non-trivial due to need to fix phamerator coordinates Edited 02 Aug, 2015 14:53

Yes I see that the current phamerator database now has nerujay and luchador out of draft stage. When I try on my local SEA 2015 image with same version of phamerator and database those phage work for me through the first 10 or so phams, so it looks like these issues might be local to your machine. From what I now understand about starterator I would suggest you try deleting all the old cache files in "/home/seastudent/.sterterator/Intermediate Files/". If that solves the issue we should probably add that to the instructions to try that first before posting about crashing phages. Edited 19 Jul, 2015 17:15
