question about uploading data through URL method
by Xiangming Ding 20 Mar '12

20 Mar '12

Hi galaxy I am a new user of galaxy. i met a problem and didnot find similar question in FAQ. I wanted to upload the data from DDBJ DRA dataset to galaxy through UTL method. The file is around 800M. However after uploading, the FASTQ file was just around 2M. So I wanted know whether it is possible to upload a large file to galaxy through URL method? or I should download the file to my pc and then uploading to galaxy through FTP method. Thanks xiangmimg

Or you can manually create the workflow in the workflow editor, starting from one of the existing ones and adding the new tools and connecting them together. Peter

Combining two workflows into one

Galaxy Team, I would like to create a workflow by combining portions of two different workflows. How do I do this in Galaxy? Thanks, Getiria Onsongo

Dear Galaxy Developer, where is the "history/workflow" file stored in the local machine?

Dear Galaxy Developer, where is the "history/workflow" file stored in the local machine? I mean the real file store in the disk instead of browser access.

wig file conversion
by Horvath, Lindsay 17 Mar '12

17 Mar '12

I am a PSU student at the College of Medicine. I have minimal bioinformatics and computer programing background. I was introduced to galaxy during televisied genomics course. I believe I am using galaxy on the cloud. I am trying to display ChIP-CHIP data on UCSC. I have downloaded the gff file (attached; NCBI/GEO # GSM413116) and uploaded it into galaxy (using get data; upload file). The initial publication converted gff file to wig file for upload into UCSC. I could not find this function in Galaxy so I tried converting to bed file instead (convert formats; gff-to-bed). When I do this and upload into UCSC I do not get the peak hight (score difference) at each site (column 6 of gff file; score--which appears to convert to all 0s in bed file), only the locations are annotated but not the score. Is there something I am doing wrong in the conversion to a bed file or alternatively is there a way to convert the intial gff file into a wig file? Any help would be greatly appreciated! Thanks, Lindsay Horvath

fastq-MCF
by Benoît REMENANT 17 Mar '12

17 Mar '12

Hi all, Does someone know fastq-MCF? We are relatively newbies in analysing RNAseq results, and we would like to use the fastq-MCF program to trim our illumina sequences (based on quality score and adapters sequences) while keeping paired reads synchronized. Unfortunately, there are some parameters we did not understand, like -s (log scale for clip pct to threshold) and -t (% occurrence threshold before clipping). Does anyone can explain us what these parameters mean? Or when I can found useful information? And do you think we have to unable the PF filtering (and why)? Thank you very much in advance if someone can help us. Benoit

Re: [galaxy-user] Read Length Distribution
by Jennifer Jackson 16 Mar '12

Hello, Other types of statistics can be generated with the "Join, Subtract and Group -> Group" tool, by adding an additional file manipulation. First run "Compute sequence length". Next run "Add column to an existing dataset" and set this to be the same value for all rows, "1" or something else simple. Nest, run "Group", with a group on the column containing the "Add column" value, and then click on "Add new Operation". Set "Type" to be "Mode" and "On column" to be the the sequence length. Very large files, usually when run with multiple operations, are occasionally to too large to run with this tool on the public main Galaxy instance. If this occurs, the first option is to simplify the query. If that doesn't work, then moving to a cloud instance would be the recommendation.

Read Length Distribution
by Elad Firnberg 16 Mar '12

16 Mar '12

Hi, Is there a tool or easy way to obtain a read length distribution on a set of 454 reads in fasta format? I can't seem to find such a tool in Galaxy. Thank you, Elad
