博主您好。初学citespace导入cnki数据时遇到一个问题:系统总是提示”No data files found.Check the following:(1)the data ditectory in the current projiect is correctly specifed;(2)data files must be named as download*.txt(3)the path and the filenames should be in English only.我按照相关说明从知网导出数据(e.g Download_6815;refworks格式),经转换形成一系列txt文本(e.g download1996_224x1unique),路径文件夹也都改成英文名了,但运行GO,仍然弹出上述提示,请给予帮助,十分感谢!
