[galaxy-user] how to use user-defined reference?
Hi everyone, I am wondering if I can use user-defined reference instead of selecting the reference genome listed in Galaxy while doing mapping. If we can, how can I choose the uploaded reference instead of selecting the reference genome? Any ideas are greatly appreciated!

[galaxy-user] How to block anonymous access and disallow user registration
Hello, I've just set up my own instance of Galaxy running in AWS and had a security question that I couldn't find an answer to on the wiki. I'd like to prevent people from hitting my public Amazon IP and using Galaxy. Is there a way to prevent anonymous users from accessing any part of Galaxy except a login prompt and have user registration be invite-only (or perhaps turn it off completely once a handful of accounts have been created)?

Re: [galaxy-user] a question about cuffdiff "values"
Hi El, > 1) what do these numbers represent? FPKM values for sample 1 and 2. Cufflinks documentation is the place to get definitions for all columns: http://cufflinks.cbcb.umd.edu/manual.html#gene_exp_diff > 2) If in the "value" column where I expect a higher number has a "value of > 10" or less mean anything or should one be selecting for values higher that > these single digit numbers > 3) And in the column of genes that might be repressed is there really a > difference between a "value of 0.1 versus something like 0.01" since that > can change my log ratios significantly--this, of course, goes back to my > first question These questions get at the challenge of interpreting FPKM values. One thing to look at is the confidence intervals (CI) produced by Cufflinks/diff. CIs that overlap 0 are, in my experience, unreliable no matter how large the FPKM. Most likely genes with FPKM values near 0 have CIs overlapping 0, which means there's likely no difference between them. However, genes with low FPKM values ( e.g. < 10) but tight CIs and > 0 should probably be included for further analysis. Another thing to look at is whether a couple highly-expressed genes are reducing FPKM values. If so, using the upper-quartile normalization option can help you get better resolution for genes expressed at low levels.

[galaxy-user] a question about cuffdiff "values"
Hello: I am a Galaxy-naive molecular, developmental biologist studying repression/derepression of early embryonic gene expression in zebrafish embryos. After attending the Galaxy meeting I returned home and worked up two mRNAseq files to determine RNA expression differences using cuffdiff between a treated and an untreated sample (i.e. data from cuffdiff under the title of "gene differential expression testing"). I downloaded the data, opened it up in an Excel file and captured all the "significant" rows. If I look at the "value 1" and "value 2" columns I find that many of the numbers are single digits. I expect that in one of the columns that the numbers will be very low (that is, less than 1) because the treatment should be inducing gene expression in a subfamily of genes that are repressed. My questions are: 1) what do these numbers represent? 2) If in the "value" column where I expect a higher number has a "value of 10" or less mean anything or should one be selecting for values higher that these single digit numbers 3) And in the column of genes that might be repressed is there really a difference between a "value of 0.1 versus something like 0.01" since that can change my log ratios significantly--this, of course, goes back to my first question I would appreciate any help I could get, sincerely, el linney Professor of Molecular Genetics and Microbiology Duke University Medical Center ___ The Galaxy User list should be used for the discussion of Galaxy analysis and other features on the public server at usegalaxy.org.

[galaxy-user] Question about Unified genotyper
I have been trying to use either Unified genotyper or Freebayes on one of the Bam file. Both are failing. 1. With Unified genotyper it give me message saying Sequences are not currently available for specified build. I have hg19 related data and using default settings (pick up hg_g1k_v37 no other option). I am not sure why it is giving me this error. 2. As an alternative I tried to run Freebayes with default setting and choosing hg19 - it i snot giving any specific message but undetr bug icon gives me -killed. Now in order to make sure my Bam is OK, I tested out side Galaxy mPile up and with in Galaxy pile up. Any suggestion why UNified genotyper is not working. If needed I can share my history.
