Data can be downloaded from Dryad, here. Please download this data and place it in the data directory before running the code. Be sure to unzip t15_copyTask_neuralData.zip and t15_pretrained_rnn_baseline.zip.
t15_copyTaskData_description.csv contains a block-by-block description of the Copy Task data, including the session date, block number, number of trials, the corpus used, and what split the data is in (train, val, or test). This file is not required for running the code, but it may be useful for understanding the data.
