Sample GSM2478906 Query DataSets for GSM2478906
Status Public on Jul 09, 2018
Title TruSeq.Lab9.SynthA
Sample type SRA
 
Source name Synthetic smallRNA; Ratiometric Pool A
Organism synthetic construct
Characteristics lab: Lab9
lib.method.detail: TruSeq
lib.method.simple: TruSeq
pool: SynthA
Extracted molecule other
Extraction protocol The RNA sample was provided as a single aliquot containing all the synthetic RNAs. 10 femtomoles of the RNA pool was used as input for each library.
Library construction protocols varied by sample (See lib.method.simple and lib.method.detail sample characteristics). TruSeq, CleanTag, NEBNext and 4N_NEXTflex protocols use the commercial kits and were optimized for sequencing of small RNAs from low-input biosamples. 4N_A, _B, _C and _D are in-house protocols using 5' and 3' adapters with 4N randomized terminal nucleotides.
 
Library strategy miRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina HiSeq 2500
 
Data processing All FASTQ files were processed through the exceRpt small RNA-seq pipeline using the Genboree Workbench tools (http://genboree.org/java-bin/workbench.jsp). Default parameters were used, except for changing "minimum read length" to 15, and uploading the FASTQ file with the synthetic pool sequences as a "Spike-in". For the subset of "4N" libraries, the "Random Barcodes Present in Samples" option was checked, and the corresponding default subsettings were used (barcode length = 4; barcode location -5p and -3p).
Genome_build: hg19 (GRCh37)
Supplementary_files_format_and_content: *_fastq.clipped.trimmed.filtered.calibratormapped.counts.txt: Tab-delimited text files contain the name of the synthetic RNA in column 1, and mapped read counts in the second. The sequence ID contains the equimolar and ratiometric pool IDs, if present in both pools; an "NA", if not. The ratiometric pool ID contains the name of the sequence, relative concentration in pool A and relative concentration in pool B, delimited by "|".
