I'm getting this error when I try:

qrmine -i transcript.txt --topics --assign -n 3

[dermatologist]

Is the transcript.txt correctly formatted?

[youssefavx]

Do you mean utf-8? Or something else? Do I need to add in some text?

[dermatologist]

Yes, basically it analyses interviews for qualitative insight. The interview transcript file is input. The format is as below:

Transcript of the first interview with John.
Any number of lines
First_Interview_John

Text of the second interview with Jane.
More text.
Second_Interview_Jane
