Dear professor, My name is Jing Liang,a graduate student in the University of Chinese Academy of Science. Recently, when I was calculating network motifs, I used the QuateXelero,but something went wrong. I made it by referring to ‘help.doc’, but there was still a problem on time. I have saved the details of the problem in Word in the form of screenshots and words, I hope to get your help. Thank you very much and look forward to your reply. Regards Liang Jing
