What does this error trace mean/say? Also, is this is an expected behavior?

How does one annotate multiple lines in Brat?

Answer 1

I think you cannot on Brat v 1.3. But here is a possible workaround, for occasional use. Replace the period in the text by a character which is not in the list of special characters understood by Brat. I use myself the interpunct (middot):

This is a second best for sure, but it works. I also tried the 'combining dot below' on a space or on a period on one of Brat's demo files, but Brat does not accept it (maybe because it's a "long" UTF-8 character?). If you don't care much about changing the text, then ";" and ":" work too.

There may be permission/ access problem in your data or work folder. you may try putting your data into the data/example folder
