Can not load multiple subjects at the same time

Hi, I have a question about the loading of subjects.

So when I followed the turorial and set the correct working directory and folder format, the participant area did not come up with the subjects' ID. So I tried to load a text file with the subjects' names. But each time the DPARSF can only read the first subject from the text file, but not the others. So I want to ask, is there a specific format of the text file we need to write so all the subjects will be included? Or is there any other solution to process all the subjects at the same time? Thanks!
