Sequential pattern mining in SPMF: Giving words as input
Thanks for using SPMF. I'm the founder of that library. Currently, SPMF does not support text files containing some text as input. Thus, users need to do some preprocessing to convert the text file to the format used by SPMF.  But in the future, it is my plan to add the feature of handling text files natively in SPMF.  It will likely be added in the next few weeks, depending on my schedule.

By the way, if you have any question about SPMF, you can also directly ask them on the forum on the SPMF website. Then, I will answer you more quickly.
