 ## Counts file
 
 For large datasets, do not use .txt files to input counts `test_counts.txt`. Please, input counts as h5ad (recommended), h5 or a path to a folder containing a 10x output with mtx/barcode/features files.

 This is the file linking bacodes/cells to clusters/cell types. This file is generated by the users after they have annotated each cluster identified by scRNA-seq data (e.g., by using packages such as Seurat and SCANPY). The file contains two columns: ‘Cell’, indicating the name of the cell; and ‘cell_type’, indicating the name of the cluster considered. Formats accepted are .csv, .txt, .tsv, .tab and .pickle.

 ## DEGs file
 
 This file is only used by is METHOD 3 `degs_analysis`. It is a .txt with two columns: the first column should be the cell type name and the second column the associated significant gene id. The remaining columns are ignored. See example [here](https://github.com/ventolab/CellphoneDB/blob/master/in/endometrium_atlas_example/endometrium_example_DEGs.tsv).
