| OR operator | ; or , | .{11;22;33} or .{11,22,33} |
| Colon operator | : or - | .{10:20} or .{10-20} |
| Reaction-time operator | :rt<“variable name”> | .{11}{9:rt<“correct_resp”>} |
| Time-condition operator | t<start # ms - stop # ms> | .{11}{t<100-1000>9} |
| Flag operator-Write artifact flag | :wa<binary #> | .{11:wa<00000001>} |

Exclude double responses. The bin descriptors look for a stimulus (e.g. 11;122;22;111) that is not followed by the event code 8 between 200-1000 ms and is followed by the event code 9 between 200-1000 ms.
