The label must correspond to \_electrodes.tsv name and all ieeg type channels are required to have a position. The reference channel name MAY be provided in the reference column. | | type | REQUIRED. Type of channel, see below for adequate keywords in this field. | | units | REQUIRED. Physical unit of the value represented in this channel, e.g., V for Volt, specified according to the [SI unit symbol](https://en.wikipedia.org/wiki/International_System_of_Units#Base_units) and possibly prefix symbol (e.g., mV, μV). For guidelines for Units and Prefixes see [Appendix V](../99-appendices/05-units.md). | | low_cutoff | REQUIRED. Frequencies used for the low pass filter applied to the channel in Hz. If no low pass filter was applied, use `n/a`. Note that anti-alias is a low pass filter, specify its frequencies here if applicable. |
