You can run zTree files using up to 10 channels per podium computer. Best practice is to use no more than 4 channels per podium computer. To do so, log on to the podium computer, go to the “c:\ztree” folder and select the sub-folder corresponding to the podium computer on which you are currently working. Within the podium folder, launch“startztree3_ch1_podium.bat” for channel 1, “startztree3_ch2_podium.bat” for channel 2, “startztree3_ch3_podium.bat” for channel 3, “startztree3_ch4_podium.bat” for channel 4, and so on. There must be a one minute lag between launching the different channels.
Note that you may only require 1 channel to run small sessions. For bigger groups, we recommend you use more channels (2-4) and split the bigger group into subgroups for each channel. For much larger groups, we recommend you use both Podium 1 and Podium 2. If you wish to launch the zTree program for the other Podium, please log in to the other Podium computer and follow the above steps.
The z-Tree program itself resides in the c:\ztree folder and any source files (treatment, questionnaire, images, config files, etc.) should be copied to this folder.
