Hi I have a couple of questions regarding RNA seq analysis. My questions are 1.I need to use a viral genome (very small, ~2kb ) as a reference genome and it is not available in Galaxy. I guess I can use this data from my history. I have a fasta file but I am not sure whether I have to do some kind of indexing or not. 2. In Tophat, default for "maximum number of alignments to be allowed" is 40. What my understanding is a single read can be aligned maximum 40 different places. I am wondering why this is 40. Is there any specific reason? If I need unique mapping, I have to use 1 instead of 40. Am I correct? Thanks SP
Hi, I have done exactly the same kind of thing for adenovirus so I can help with it. In answer to question 1 you do not need to index it will be done for you when tophat is called. Secondly you should leave the 40 multihits as it is and post analysis filter out the multihits - this will allow you to determine if you do have a multihit problem or not and if so whether it is a big problem and where it is on the genome. I have a workflow on Galaxy which you can use called "Bristol workflow to get sorted unique proper pair mapped reads". If you plug in your sam file it should give you files listing only unique hits and those which map more than once. This workflow assumes you have paired end data but it can be modified to work with single end reads as well. Hope this helps. Best Wishes, David. __________________________________ Dr David A.

Hi David, Thanks!When I tried to run Tophat, it doesn't recognise my FASTA file and it says "History does not include a dataset of the required format / build". Do you have any thoughts about this? Now it makes more sense about "multihits". Thanks for sharing your workflow. With regards Sumathy On May 6 2011, David Matthews wrote:

Hello I was able to run RNA seq data against a custom build genome. How can I visualize the results. I tried via trackster and unfortunately I couldn't. Can you help me? Thanks Sumathy
There are many ways. I typically use IGV. It needs a sam file, so I first convert the bam to sam in galaxy, then download the sam file. In IGV, I upload the reference and the sam file, then use IGVtools to index the sam file, then I can visualize the data. Austin On Fri, May 6, 2011 at 5:30 PM, <puvan001@umn.edu> wrote:

One of the problem is IGV dont have option of creating index file so one has to create index file in Galaxy first to view in IGV. Jim I have been using IGV 2 beta version it is great work but How hard is to include index functionality with in IGV.

Hi Vasu, I'm going to add the function to index BAM files soon, using Picard. In the beginning.... there was no java BAM reader, only SAM, and I added the index then. Indexed BAMs came along later, but that's probably more than you want to know... I think most people will still use Galaxy to index as it can take a long time, but I agree with you on the convenience factor. Jim On May 6, 2011, at 9:36 PM, vasu punj wrote:

Hi I may be doing in a wrong way. I clicked trackster and I added the custom build genome. Since it is a very small genome (~2kb), I considered this as a single contig. Then I cliked "add tracks" and added my data file. But I got a message "no data for this contig. Whenever I used built in genomes I did not have any problem. I guess I am doing something wrong here.

Sumathy,
What kind of problems are you having with Trackster?

Hello
I was able to run RNA seq data against a custom build genome. How can I visualize the results. I tried via trackster and unfortunately I couldn't. Can you help me?
Thanks

Sumathy, It sounds like you're on the right track. To visualize data for a custom build in Trackster, you need to create a custom build and use that in Trackster: (1) using the top tabs in Galaxy, go to User --> Custom Builds; (2) add a new build with the length info as follows: <contig_name> <length> Important note: you'll need to make sure that your contig name matches the one used in your fasta file. This is my best guess about what's causing problems for you. (3) Create a Trackster visualization using the custom build and add your dataset. Let us know if you have more questions/problems.
