In NEURON simulator, suppose I graph the value of a variable (i.e. soma.v(0.5)) over time. How do I save the values in the graph to a file?

    $\begingroup$ I'm voting to close this question as off-topic because the question is about the use of software. I reckon an answer to any question at this site should at least contain an element touching on CogSci. $\endgroup$

    $\begingroup$ Should probably be discussed on Meta, but software that is CogSci specific could reasonably be on-topic. $\endgroup$

    $\begingroup$ I picked CogSci because the software tag explicitly mentions the use of software: "Software": For questions regarding the use and selection of computer programs designated for instruction, experimentation, and data processing. $\endgroup$

Not intuitive, but to save the value of a curve plotted in a graph:

  1. Right click the graph window, and choose "Pick Vector"
  2. Click on the desired curve (it should change color i.e. to red)
  3. In the NEURON Main Menu > Vector > Save to File
  4. Type in the file name > Save
  5. File will have two columns, first one for X-axis values (i.e. time) and second for the Y-axis (i.e. voltage)
