Mapping

Input
yap demultiplex output directory, refer to as {output_dir} below.
Cell batches and snakemake
During demultiplex, cells are divided into small batches based on their PCR index. FASTQ files of each batch are saved together in a sub-directory of the {output_dir} . Each of the sub-directory is mapped together in a single job, all the steps that need to be done are written in the {output_dir}/{sub_dir}/Snakefile , a file needed by snakemake, and contain all the commands to map the files in this sub-directory. 
Here is a single command used to execute the Snakefile, but you don't need to do this by yourself (see below):
1
# to map cells in a single sub directory
2
​
3
snakemake \
4
-d {output_dir}/{sub_dir} \
5
--snakefile {output_dir}/{sub_dir}/Snakefile \
6
-j {parallel_cores_to_use_for_this_job}

​What is snakemake?​
Execute snakemake commands
In the {output_dir}/snakemake , you should be able to find a list of snakemake commands like the above, one command for each PCR index sub-directory. You have three ways to execute these commands.
