In a similar way as described above you use a combination ofĪrithmetic functions to zero (or NaN) those areas you like to remove, based on time windows. Note: if you divide the source channel by the combined function you get NaNs for the out of range data.ī) you like to remove data you marked manually: By multiplying it with the source channel the good data remain while the out of range data become 0. When combining those functions one gets a trace with 0įor the out of range data and 1 where the signal is good. Threshold() is then used to create a 0 or 1 wave form. Detailed information about these functions can be found in the LabChart Help documentation.įunction identifies the regions that are within the lower and upper limits (regions of good data become 1, out of range data become 0).
(set zero) regions where data are out of range. Using arithmetics you use a combination of three functions Window(), Smoothsec() and Threshold() to hide Out_of_range data.adicht (download here). to process your data so that portions of your recording become zero or NaNĪ) you like to remove Out of Range Data:For reference see attached example file Hide Please note, this will delete this time of recording from all channels.ĭeleting is no option you can use Channel Calculations > Arithmetics. Simply delete: select the area and choose Edit > Clear Selection. If you like to remove portions of data, for example artifacts, to exclude them from your data analysis there are different ways to achieve this.
