    UCSC mm10 gtf file

    Hi,
    I have dowloaded UCSC hg19 gtf files from Galaxy



    The resulting file looks like that:
    $ head hg19_genes.gtf
    Code:
    chr1	unknown	exon	11874	12227	.	+	.	gene_id "DDX11L1"; transcript_id "NR_046018_1"; gene_name "DDX11L1"; tss_id "TSS14523";
    chr1	unknown	exon	12613	12721	.	+	.	gene_id "DDX11L1"; transcript_id "NR_046018_1"; gene_name "DDX11L1"; tss_id "TSS14523";
    chr1	unknown	exon	13221	14408	.	+	.	gene_id "DDX11L1"; transcript_id "NR_046018_1"; gene_name "DDX11L1"; tss_id "TSS14523";
    chr1	unknown	exon	14362	14829	.	-	.	gene_id "WASH7P"; transcript_id "NR_024540"; gene_name "WASH7P"; tss_id "TSS7359";
    chr1	unknown	exon	14970	15038	.	-	.	gene_id "WASH7P"; transcript_id "NR_024540"; gene_name "WASH7P"; tss_id "TSS7359";
    chr1	unknown	exon	15796	15947	.	-	.	gene_id "WASH7P"; transcript_id "NR_024540"; gene_name "WASH7P"; tss_id "TSS7359";
    chr1	unknown	exon	16607	16765	.	-	.	gene_id "WASH7P"; transcript_id "NR_024540"; gene_name "WASH7P"; tss_id "TSS7359";
    chr1	unknown	exon	16858	17055	.	-	.	gene_id "WASH7P"; transcript_id "NR_024540"; gene_name "WASH7P"; tss_id "TSS7359";
    chr1	unknown	exon	17233	17368	.	-	.	gene_id "WASH7P"; transcript_id "NR_024540"; gene_name "WASH7P"; tss_id "TSS7359";
    chr1	unknown	exon	17606	17742	.	-	.	gene_id "WASH7P"; transcript_id "NR_024540"; gene_name "WASH7P"; tss_id "TSS7359";

    When obtaining the same file from UCSC Tables, the file looks somewhat different. First 3 rows are similar and thereafter things don't exactly match.....

    $ head hg19_ucsc_table.gtf
    Code:
    chr1	hg19_knownGene	exon	11874	12227	0.000000	+	.	gene_id "uc001aaa.3"; transcript_id "uc001aaa.3"; 
    chr1	hg19_knownGene	exon	12613	12721	0.000000	+	.	gene_id "uc001aaa.3"; transcript_id "uc001aaa.3"; 
    chr1	hg19_knownGene	exon	13221	14409	0.000000	+	.	gene_id "uc001aaa.3"; transcript_id "uc001aaa.3"; 
    chr1	hg19_knownGene	exon	11874	12227	0.000000	+	.	gene_id "uc010nxr.1"; transcript_id "uc010nxr.1"; 
    chr1	hg19_knownGene	exon	12646	12697	0.000000	+	.	gene_id "uc010nxr.1"; transcript_id "uc010nxr.1"; 
    chr1	hg19_knownGene	exon	13221	14409	0.000000	+	.	gene_id "uc010nxr.1"; transcript_id "uc010nxr.1"; 
    chr1	hg19_knownGene	start_codon	12190	12192	0.000000	+	.	gene_id "uc010nxq.1"; transcript_id "uc010nxq.1"; 
    chr1	hg19_knownGene	CDS	12190	12227	0.000000	+	0	gene_id "uc010nxq.1"; transcript_id "uc010nxq.1"; 
    chr1	hg19_knownGene	exon	11874	12227	0.000000	+	.	gene_id "uc010nxq.1"; transcript_id "uc010nxq.1"; 
    chr1	hg19_knownGene	CDS	12595	12721	0.000000	+	1	gene_id "uc010nxq.1"; transcript_id "uc010nxq.1";

    So, when I grep out miRNA genes from the first gtf file obtained through Galaxy (hg19_genes.gtf ), I get a gtf file with only miRNA genes.
    command:
    Code:
    $cat hg19_genes.gtf | grep "MIR" > hg19_miRNA.gtf
    this command, however, does not work for the file I got from UCSC Tables (hg19_ucsc_table.gtf ). I guess the gene_id's are just denoted to contain miR/MIR symbol.

    So, my question:
    I would like to obtain miRNA gtf files for mm10 in UCSC format (I've used UCSC mm10 for mapping).
    In Galaxy, there is only UCSC mm9 gtf file (https://usegalaxy.org/library_common...9490a8b6c89961).
    How can I obtain UCSC mm10.gtf in a format, where I could grep out the miRNA genes????

    You can use the table browser at UCSC to export mm10 annotation in GTF format.

    If you happen to have access to iGenomes mm10 download http://support.illumina.com/sequenci...e/igenome.html the GTF file would be in Annotations sub-directory.

      Hi heso,

      The format of the file you downloaded from Galaxy looks like
      the iGenomes files.

        I got it fixed now. I used this site for downloading.
        ftp://ussd-ftp.illumina.com/Mus_musculus/UCSC/mm10/

        There I found the gtf in the format I wanted.
        Thanks everybody

          Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

          Nine Things a Sample Prep Scientist Thinks About Before Sequencing
          by SEQadmin2


          I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

          Here are nine questions we think about, in roughly the order they matter, before...
