For instance, train times 50ms and 350ms give below chance performance at test time 250ms and 150ms, respectively. \r\n![gat_scores_figure](https://cloud.githubusercontent.com/assets/4253050/8956269/52d4f202-35f4-11e5-9371-4f7039ddadb4.png)\r\nLooking at the topomaps, we can see a patterns inversion between these train and test times.\r\n![gat_patterns_figure](https://cloud.githubusercontent.com/assets/4253050/8956272/56dc99cc-35f4-11e5-87e0-79764373bf8b.png)\r\nFor me, this observation explain below chance performance and make sense actually.\r\nDo you think it would be useful to create an example of these plots?\r\n\r\nRomain\r\n"}}
