Extracted molecule total RNA
Extraction protocol Single cells were captured on a C1 system, using a 5-10 um mRNA Seq IFC according to manufacturer’s instructions (Fluidigm, South San Francisco, CA). Full-length cDNA was prepared using SMARTer Ultra Low RNA Kit for the Fluidigm C1 System (Clontech, Mountain View, CA).
Libraries were prepared from amplified cDNA using the NexteraXT kit according to manufacturer’s instructions (Illumina, San Diego, CA).
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
 
Data processing Base-calling was performed automatically in Illumina BaseSpace after sequencing; FASTQ reads were trimmed in Galaxy in two steps: 1) hard-trimming to remove 1 3'-end base (FASTQ Trimmer tool, v.1.0.0); 2) quality trimming from both ends until minimum base quality for each read >= 30 (FASTQ Quality Trimmer tool, v.1.0.0).
Reads were aligned in Galaxy using bowtie and TopHat (Tophat for Illumina tool, v.1.5.0); duplicate alignments were marked and removed using Picard MarkDuplicates.
Read counts per Ensembl gene ID were estimated in Galaxy using htseq-count (htseq-count tool, v.0.4.1).
Sequencing, alignment, and quantitation metrics were obtained for FASTQ, BAM/SAM, and count files in Galaxy using FastQC, Picard, TopHat, Samtools, and htseq-count.
Samples were selected for further analysis by using these criteria: log10(PF_ALIGNED_BASES)>6.5, MEDIAN_CV_COVERAGE<1 & MEDIAN_CV_COVERAGE >0.4.
Genes expressed (counts per million >1) in less than 3 samples were removed. Data normalization (TMM) and differential expression analysis were performed in R using "edgeR" package.
Genome_build: GRCh38
Supplementary_files_format_and_content: raw_counts_T1D_single_cell.txt is a tab-delimited matrix. The first column contains Ensembl gene IDs The remaining columns include raw read counts assigned for each library. Outlier samples have been removed but data have not been gene filtered or normalized.
