To adjust the x-axis, enter “setaxis bottom 0, #” in the text command window, where # is the desired number of seconds. To adjust the y-axis, go to the text command window and enter “setaxis left -1, 1”. To auto scale both the y-axis and the x-axis, enter “setaxis/a” in the text command window.Click on the button at the bottom left corner of the window. Select the appropriate channel, for example “Input 2”, from the list under “Y Waves” and select “calculated” from the list under “X Waves”.Go to the window menu at the top of the tool bar. If it does not, close the graph by clicking on the button in the upper right corner of the window. For example if you are using channel 2 to collect data, the graph title should say “Graph0: Input 2”. For example if the instrument scans every 0.1 sec, the number of scans should be ten times the anticipated run time (a 10 minute run is 1200 seconds, or 12000 scans). Next, click on the button and select the appropriate number of scans for the instrument to make by typing that number into the white box.Look inside the break-out box to make sure that the input channel in the box is the same channel selected in the software (should be channel #2). A data table, the channel selector, a graph, and text command window should be visible on the screen. Common run parameters include Channel (wired as #2), Input (same as channel, #2), Gain (1.0), Scan Interval (0.1sec), and Number of Samples. Otherwise select Recent Experiments and click on the file containing your run parameters. If this is your first time using IGOR Pro YOU MUST CONSULT THE USER’S MANUAL TO ESTABLISH THE INITIAL DATA COLLECTION PARAMETERS. Then go to File > Save Experiment As. Set up all the windows the way you like them, and set up any stimuli youll need for that type of recording session.
