Please help to understand the square root of Jensen-Shannon divergence
by Du, Jianguang 06 Sep '12

06 Sep '12

Dear All, I am looking for the differential splicing events between cell types. However the Cuffdiff gives output using "the square root of Jensen-shannon divergence" to measure the difference. Although I tried my best to understand "the definition of the square root of Jensen-shannon divergence", I still could not understand the meaning of a specific value of "the square root of Jensen-shannon divergence". I would appreciate it very much if anyone let me know how to covert "the square root of Jensen-shannon divergence" into "fold". For example, how much "the square root of Jensen-shannon divergence" is "2 fold difference" equal to. Thanks in advance. Jianguang

Tophat settings
by Du, Jianguang 06 Sep '12

06 Sep '12

Dear All, I am not so sure about two Tophat settings. Please help. 1) "Number of mismatches allowed in the initial read mapping" Based on the documantation, my understanding is: the reads are re-aligned to transcriptome/genome if the mismatches in the initial alignment is more than the set number (for example, the default setting is 2). In other words, the re-aligning will continue until the mismatches is equal to or below the set number. Is my understanding correct? If I am right, I have one worry: will Tophat stop re-aligning if the mismatch is below 2 (if I use the default setting). If it is true, the read will not be aligned to where it belongs to (with 0 mismatch). 2) "Number of mismatches allowed in each segment alignment for reads mapped independently" Does this mean that the reads will be cut into segments if the mismatches of alignment is more than the set number? Thanks in advance. Jianguang

Tools won't go away even after deleting it from tool_conf.xml
by Makis Ladoukakis 06 Sep '12

06 Sep '12

Dear Galaxy users, Has anyone experienced this problem before? In my local instance of Galaxy on a server I've deleted the path of almost all sections with their corresponding tools from tool_conf.xml (wanting to leave my own customized section) but after a restart and a new run of the run.sh there are still two of them (SNP/WGA: Data; Filters and Phenotype Association) left in the tool list with their first tool also appearing. Is there a special setting for those two? Can anyone help me? Thank you, Efthymios Ladoukakis

Downloading a zip file .......
by Neil.Burdett＠csiro.au 04 Sep '12

04 Sep '12

Hi I can modify the upload.py file by commenting out the uncompress stuff and hence upload a zip file containing many files. However, when I click on the "save" icon and try and download the file, it seems the tar file is corrupt. I can only assume that during the upload the contents of the files in the zip are somehow being modified? Is this correct? Do you know of any other files I need to modify to be able to download a zip file and not be corrupt? Thanks Neil

Hi, Does MACS remove duplicate reads automatically during the peak calling? I'm running controls for all the samples. Thanks for your help, Yanina

No reference genome listed for NGS: Mapping Map with TMAP for Ion Torrent
by Catherine Dumur 31 Aug '12

31 Aug '12

The "Select a reference genome" popup in the NGS mapping section is empty for TMAP for Ion Torrent tool (version 0.0.19) on the Galaxy Web Portal (I am using Galaxy Test, since I only have Ion Torrent data, and the TMAP tool is only on Galaxy Test). How can I populate it? Thank you very much in advance for any help you can provide! Cathy Catherine I.
