scRNAseq: Count and Load with Cell Ranger
View on GitHub
Download RO-Crate
Run on GalaxyTakes fastqs and reference data, to produce a single cell counts matrix into and save in annData format - adding a column called sample with the sample name.
Inputs
| ID | Name | Description | Type |
|---|---|---|---|
| Fastqs for one sample | Fastqs for one sample | Typically the Forward reads are labelled _R1, barcodes. R2 is Reverse, mRNA sequences. List should contain seq for one biological sample only. |
|
| Reference genome | Reference genome | Built in reference dataset to use (human or mouse only) |
|
| Sample | Sample | Short, unique sample name |
|

| 7 | Text transformation | This step replaces the first line with a header. Because the annotated data matrix also had a header, this works. toolshed.g2.bx.psu.edu/repos/bgruening/text_processing/tp_sed_tool/1.1.1 |
| 8 | Loaded Anndata with Sample name | AnnData object with supplied sample id. toolshed.g2.bx.psu.edu/repos/iuc/anndata_manipulate/anndata_manipulate/0.7.5+galaxy1 |

This collection houses some scanpy-based scRNAseq workflows on galaxy Australia.
The aim of these workflows is to handle the routine ‘boring’ part of single cell RNAseq data processing. It will produces an ‘AnnData’ object, which can then be used as a base for downstream analysis – either within galaxy or outside of it. AnnData is a standard format used by the ‘scanpy’ python package.
These workflows represent just one way of processing data for a ‘typical’ scRNAseq experiment – there are many ...
