Dataset Overview:
This dataset contains a typical example of Seq-Scope dataset that investigators would generate after examining the initial sequence data. If the quality of the initial Seq-Scope dataset looks great, one may decide to sequence the library much more deeply to maximize the information content. (see NovaScope tutorial at https://seqscope.github.io/NovaScope/ for more details). The spatial barcode sequences and the initial version of the sequenced cDNA library are deposited in a separate repository, which is described in the NovaScope documentation (https://seqscope.github.io/NovaScope/). This data repository contains a deeper sequencing of the same library.

Methodology:
This dataset contains the sequence of cDNA libraries, attached with spatial barcodes, of mouse liver tissue section prepared by the Seq-Scope methodology (https://doi.org/10.1016/j.cell.2021.05.010). Adult mouse liver tissue was previously collected from 8-week-old male C57BL/6 wild-type mice immediately after CO2 euthanasia. The tissue was embedded in an optical cutting temperature (OCT) compound on cooled isopentane (2-methylbutane) in a liquid nitrogen bath and stored at –80 °C. The tissue was placed on a section of NovaSeq 6000 flowcell, which was sequenced according to the Seq-Scope protocol. After mRNA release and reverse transcription, the cDNA library was deeply sequenced using Illumina NovaSeq X System.

Files contained here:
Paired-end FASTQ files for deeply sequenced Seq-Scope library of liver section. There are 7 pairs of FASTQ files. This should be added to the shallow liver dataset deposited in the separate library (https://doi.org/10.5281/zenodo.10835761). MD5sums for each FASTQ file are also available.
