The other feature \"ohmic_input_resistance\" is extremely off. It seems to be because it uses the \"voltage_deflection\" feature in the calculation, and that feature seems to be picking up a tiny noise blip at the beginning of the trace (3 mV) and ignoring the 24 mV offset produced by the stimulus later on.\r\nvoltage_deflection = 0.0038342857142978914\r\nohmic_input_resistance = 0.037602023420651907\r\n![image](https://user-images.githubusercontent.com/6456664/29530956-469cbc0e-8674-11e7-8597-a01d2dbf17e2.png)\r\n\r\nHow can I access the E29 feature or is there a way to fix the voltage_deflection calculation?
