 ## 1. Building cost matrix
 Here, we want to calculate cost matrix between different ROIs in two atlases. Then, we have to specify the names of two atlases with `-s` and `-t` and the task we want to learn mappings with `-task` .
 ```console
-python build_cost_matrix.py -s craddock -t shen -task rest1
+python build_cost_matrix.py -s craddock -t shen
 ```
 The output will be stored in `cost_source_target.csv` with `n` rows and`m` columns indicating number of ROIs in source and target respectively. 
 
 ## 2. Finding mappings
 Now, we can specify two atlases and the cost matrix derived from previous step to obtain optimal transport mapping between these two. 
 ```console
-python build_mapping.py -s craddock -t shen -task rest1
+python build_mapping.py -s craddock -t shen
 ```
 The output will be stored in `T_source_target.csv` with `n` rows and`m` columns indicating number of ROIs in source and target respectively. Each row is a probability distribution exhibiting optimum assignment of values from the appropriate node to target nodes.
