Help with Summary Statistics
by D. A. Cowart 23 May '14

23 May '14

Hello, I am attempting to use Galaxy to calculate the mean sequence read length and identify the range of read lengths for my 454 data. The data has already been organized and sorted by species. The format of the data is as follows: >HD4AU5D01BHBCQCTCTCTCTCTCTCTCTCTCTCTCTCTCTCTCTCTCTCTCTCTC >HD4AU5D01A093MCTCTGTCGCTCTGTCTCTCTTCTCTCTCTCTCTCTCT etc...for each species I have attempted to use the "Summary Statistics" button, however it appears to only be for numerical data and not sequence data. Is this tool/task available via Galaxy? Thank you, Dominique Cowart User name: dac330

from Galaxy to Megan
by Judith van Bleijswijk 10 Oct '12

10 Oct '12

Dear Galaxy users that also use Megan, I hope you can help me combining Galaxy with Megan4. I followed the Galaxy metagenome workflow (author aun1) on shotgun DNA 454 sequences of two samples that I would like to compare. The results are two nice trees and tables with the lowest taxonomic ranks for the two samples. Besides the taxonomy I am also interested in the functions and I would like to use Megan4 (with SEED and KEGG classification) for this purpose. I tried to import a Galaxy file (.tabular) with c1 =high quality segment name and c2-c13 =blasthit results and a Galaxy fasta file with the high quality segment names and sequences. This does not work and I receive the message parsing failed, no reads found. I am interested to know how you solved this issue and which files in the Galaxy metagenome workflow you use to import into Megan4. Or maybe there is other software that you use to compare suits of functional genes in your metagenome datasets? Regards, Judith van Bleijswijk

Hi everyone, When I tried to upload my files using Filezilla, I got the error message "530 Sorry, the maximum number of clients (3) for this user are already connected." Can anyone give me some suggestions how to solve this problem? I have been stuck here for a whole day. Thanks very much! Yan

What is the minimum Quality should I set for Filter FASTQ?
by Du, Jianguang 13 Sep '12

13 Sep '12

Dear All, I am analysing RNA-seq datasets for differential splicing events between cell types. Some of my reads contain bed nucleotides, should I run Filter FASTQ to remove these "not so good" reads? If I do need to, what is the "Minimum Quality" should I set for the Filter? Thanks. Jianguang

interupted running jobs restart
by petr 12 Sep '12

12 Sep '12

We are running galaxy on pbs cluster. In out setting some jobs can take several weeks to finish and it is virtually impossible to wait for suitable moment when server can be restarted or turn down without interrupting running tasks. Is there an option on server setting which will enable jobs which were interrupted because of the server maintenance to run again after the cluster is back on? best regards. Petr

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.

Should I "use raw junction" and "Only look for supplied junctions"
by Du, Jianguang 29 Aug '12

29 Aug '12

Dear All, I have two more questions about settings for Tophat. My aim is to look for the defferential splicing events between cell types. After I checked "Use Own Junctions", three more options came out: 1) "Use Gene Annotation Model" 2) "Use raw Junctions" 3) "Only look for supplied junctions" As instructed by Jen, I checked "Use Gene Annotation Model", and input iGenome mm9 genes.gtf as "Gene Model Annotations". However, I am not sure if I should choose to "Use raw junctions" and "only look for supplied junctions". Please help me set up these two options. Thanks. Jianguang
