| StartStop | - Cling Time(whole animal) | |||
| Hold | StartStop | - Total number of Holds- Holds duration | - Mean duration per Hold | |
| Step without Touches | StartStop | XY startXY end | - Total number of Steps without Touches- Steps duration- Steps distance | - Mean Step duration- Mean Step length- Mean Step velocity- Number of Trains- Steps per Train- Regularity Index |
| TouchStep with Touch(es) | Time of occurrenceStartStop | XY startXY end | - Total number of Touches- Total number of Steps with Touches | |
| Wall Contact | StartStop | - Total number of Wall Contacts- Wall Contacts duration | ||
The table shows the principle metrics extracted from the time histograms in a frame-byframe manner.
After definition of the overarching behavioral Categories and their identification on the video, Primary and Secondary proxies for each paw were calculated.
For definition of parameters, see Material and Methods and Table 2.
