The URDA-EEG Data Cleaning tool uses a systems of credits.  When the algorithm is used, credits are subtracted from the user’s account.  The user may add credits to their account using our shopping cart system (to be added later).  The price to clean a dataset is approximately $5CAD. Each new account starts with 99 credits to give the user an opportunity to evaluate the cleaning methods provided.  Once an account reaches zero credits, or if there are insufficient credits to clean a dataset, the user is required to purchase additional credits to continue to use this service.

Does it cost more to try multiple different cleaning algorithms on the same dataset?

We have implemented the system in such a way that the same dataset can be cleaned multiple times and credits for cleaning that dataset will only be subtracted ones from the account.
