| Extraction protocol |
DRG, oocytes, hESC, HEK293T, ARPE, mESC, hESC_drived_organoid were dissected and dissociated into single cells. hESC, HEK293T, ARPE, mESC, hESC_drived_organoid were dissected respectively and mixed together.
The scRCAT-seq library was prepared according to the scRCAT-seq protocol.
The smart-seq2 library was prepared according to the smart-seq2 protocol.
The Iso-Seq library was prepared according to the Isoform Sequencing protocol.

| Description |
applying single cell method to ERCC
|
| Data processing |
Illumina Casava1.7 software used for basecalling.
5' and 3' sequences were extracted from paired-end sequences using Perl, Python and shell script
5' and 3' sequences were aligned to mm10, using STAR (2.6.1a), with with parameters (--outFilterMultimapNmax 1 --outFilterScoreMinOverLread 0.6 --outFilterMatchNminOverLread 0.6).
Peaks were called with CAGEr (v 1.24.0) .
For smart-seq2 data, sequenced reads were trimmed for adaptor sequence using cutapapt (v 1.18) and aligned to mm10 using STAR with with parameters as described above.
For Iso-seq data, sequence data were processed using the SMRTlink5.0 software. Circular consensus sequence (CCS) was generated from subread BAM files, parameters: min_length 200, max_drop_fraction 0.8, no_polish TRUE, min_zscore -9999, min_passes 1, min_predicted_accuracy 0.8, max_length 18000. CCS.BAM files were classified into full length and non-full length reads using pbclassify.py script, ignore polyA false, minSeq Length 200. Non-full length and full-length fasta files produced were then fed into the cluster step, which does isoform-level clustering(ICE), followed by final Arrow polishing, hq_quiver_min_accuracy 0.99, bin_by_primer false, bin_size_kb 1, qv_trim_5p 100, qv_trim_3p 30.
Additional nucleotide errors in consensus reads were corrected using the Illumina RNA seq data with the software LoRDEC.
consensus reads were aligned to reference Genome using GMAP with parameters --no-chimeras --cross-species --expand-offsets 1 –B 5 –K 50000 –f samse –n 1 against reference genome.
Gene structure analysis was performed using TAPIS pipeline.
Genome_build: mm10
