Sample GSM2595507 Query DataSets for GSM2595507
Status Public on May 01, 2018
Title WT rep2
Sample type SRA
 
Source name Left ventricle posterior wall
Organism Mus musculus
Characteristics strain: C57BL6/J
tissue: Left ventricle posterior wall
age: 30 weeks
Growth protocol Mice were generated using a het-het breeding strategy and housed at 24degC for 30 weeks.
Extracted molecule polyA RNA
Extraction protocol Mice were anethetized with TBE and then hearts were flash frozen in liquid nitogen. Total RNA was extracted usign trizol with a quiagen column cleanup with on column DNAse.
200ng of DNase-treated total RNA with a RNA integrity number greater than 7 was used to generate polyA-enriched mRNA libraries using KAPA Stranded mRNA sample kits with indexed adaptors (Roche; Basel, Switzerland).
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 3000
 
Description 3472-MJL-5_1
Data processing Illumina HiSeq300 reads were converted to FASTQ files using the Bcl2fastq2 conversion software.
Read quality was checked using FastQCv0.11.5. TopHat v2.1.0 was then used for read allignment Tool Parameters Is this single-end or paired-end data? paired_collection RNA-Seq FASTQ paired reads No dataset collection. Mean Inner Distance between Mate Pairs 300 Std. Dev for Distance between Mate Pairs 20 Report discordant pair alignments? Yes Use a built in reference genome or own from your history indexed Select a reference genome mm10 TopHat settings to use full Max realign edit distance 1000 Max edit distance 2 Library Type FR First Strand Final read mismatches 2 Use bowtie -n mode No Anchor length (at least 3) 8 Maximum number of mismatches that can appear in the anchor region of spliced alignment 0 The minimum intron length 70 The maximum intron length 500000 Allow indel search Yes Max insertion length. 3 Max deletion length. 3 Maximum number of alignments to be allowed 20 Minimum intron length that may be found during split-segment (default) search 50 Maximum intron length that may be found during split-segment (default) search 500000 Number of mismatches allowed in each segment alignment for reads mapped independently 2 Minimum length of read segments 25 Output unmapped reads False Do you want to supply your own junction data Yes Use Gene Annotation Model Yes Gene Model Annotations 220: UCSC Main on Mouse: refGene (genome) Use Raw Junctions No Only look for supplied junctions No Use coverage-based search for junctions auto Use Microexon Search No Do Fusion Search No Set Bowtie2 settings No Specify read group? no Job Resource Parameters no
