Spatial analysis

Getting started with spatial data
Check with the core to get the following information
Files: These are specific to each run
Cytassist images
Polaris images
CSV files related to the run which has well number, slide serial number and and other information
Figure out the method, sequencing chemistry and other specifics of the run
Index barcodes if you are running bcl2fastq
Fastq files if you are not running bcl2fastq
Download the following files from 10X website
Reference genome -
Run space ranger mkfastq or bcl2fastq to get the fastq files
If you already have fastq, skip this step
Create Alignment files
Using Loupe browser, depending on the type of assay (ex: Visium vs Visium HD), align cytassist and the polaris images
You also need to know their well ID which can be found from the csv files you get from spatial core
Output is a JSON file
You might have to edit the json file to include the right slide serial number and well for visium.
For visium HD, this is not needed
Run space ranger count
Run it on each area separately
Input requirements: fastq files, reference file, probe id file, alignment json for each sample, cytassist and polaris scans for each sample.
