 # Peak calling
 In scRNA-seq we always have the standard set of genes (usually downloaded from public databases) to quantify the expression levels. For scATAC-seq, there are no such reference open chromatin regions because the regions of chromatin accessibility are tissue dependent. Hence, we first have to detect open chromatin regions. There are several ways of doing this. The most common ways are the following:
 * Find a published bulk ATAC-seq data that is the closest to your scATAC-seq data and use the regions from the bulk ATAC-seq data
-* Chumk the genome into equal-sized bins and use these bins as reference locations for quantification
+* Chunk the genome into equal-sized bins and use these bins as reference locations for quantification
 * Combine the data from all the cells of the scATAC-seq data together and detect open chromatin regions from the data. Later use these detected regions for quantification
 
 In this tutorial, we opt for the 3rd option.
