Python error when running Bowtie for Illumina

by Weng Khong Lim

Hi all, I'm new to next-gen sequencing, so please be gentle. I've just received a pair of Illumina FASTQ files from the sequencing facility and intend to map them to the hg19 reference genome. I first used the FASTQ Groomer utility to convert the reads into Sanger reads. However, when running Bowtie for Illumina on the resulting dataset under default settings, I received the following error: An error occurred running this job: *Error aligning sequence. requested number of bytes is more than a Python string can hold* * * Can someone help point out my mistake? My history is accessible at http://main.g2.bx.psu.edu/u/wengkhong_lim/h/chip-seq-pilot-batch Appreciate the help!

problems accessing the sequences through genome browser

by pande

Dear Galaxy, I have some genomic intervals for the human genome and want to extract the same for the mouse.So, I used the MAF pairwise alignment tool. But, interestingly, the associated sequences are not to be found at all through the genome browser, for file that galaxy generated for me. Here are a few first alignments from the sample: ##maf version=1 a score=5002 s hg18.chr1 1820410 11 + 247249719 GGATCCAG-------ATG s mm9.chr4 769022 18 - 155630120 GAAACAAGGTGTTCCATG a score=20688 s hg18.chr1 2077163 10 + 247249719 TTTTCTTTTC s mm9.chr4 969004 10 - 155630120 CTTTCTTACC a score=15289 s hg18.chr1 2316453 90 + 247249719 CTCAGGTGAATTCCTCATGGCATCACAGCAGTGTTGAAA-----TAGGAGCAGATACG-TTACCTCCGC--TTGCCAGATAAGAAACTGGGACGCAGA s mm9.chr4 1172933 98 - 155630120 TTACAGTGAATTCTGCCTGGGATCCGTGCAGCATTGGAAATGGCTAGGGGCAGATAGGGTCACCTTCACAGTTGCTAGATAAGAAACAGGGTCGCGGA a score=20716 s hg18.chr1 2526225 31 + 247249719 CTTCCT-CTGGGCTTGGTCATCCTTCAAAGTC s mm9.chr4 1369046 32 - 155630120 CTTCCTCCTGGTCCCAACCATCTGTCAGATCC I just want the sequences from the mouse genome and extended up to 120 base pairs from the co-ordinate mentioned in the maf file. It only generates NNNNNNNNNNNNN....I was wondering how could Galaxy retrieve it, while I can't see the same in the genome browser. Kindly help. Amit.

Comparative analysis

by Kevin S Lang

I need to compare genome sequences of several Salmonella enterica serovars. I will be looking for regions of insertions and deletions between the strains. As well as SNPs comparisons in certain genes. Is Galaxy a good tool to use for this? -K -- Kevin Lang Junior Scientist Singer Lab of Epidemiology University of Minnesota Dept of Veterinary BioScience Lab# 612-625-9266 Cell# 612-385-5410

(no subject)

by CCT Hindmarch, Henry Wellcome Laboratories Integrated Neuroscienc

Hi, I am playing with Galaxy ahead of getting ChipSeq data and it looks brilliant (thanks)... I wonder whether It is possible to input a list of genes from a standard microarray experiment, identify the promotor regions of each gene and then work out which Transcription factor binding sites are contained in this gene list? Maybe a silly question, but this would be very useful information for me...

downloading processed data

by Carlos Infante

Dear Galaxy, I use the web version of Galaxy to process my reads for quality control and then I would like to download the processed reads to run alignments locally or on our cluster. If I click "Save" in the History side panel, the download begins but then fails near completion, possibly because the download times out? Is there a way to compress the reads within Galaxy and then download the compressed file, or is there a more efficient way to retrieve my data off the Galaxy server? Thanks, Carlos

tool config and fixed output file names

by Bossers, Alex

Hi all, I am probably missing something very obvious. I am struggling to make a tool config file (and/or perl/bash wrapper) that runs some tools that have several input files (no problem) but also several FIXED name output files. I am able to give it some prefix but the extensions (if any) cannot be changed. Any help appreciated how to link/get this in $output. Alex
