Dear Lionel,
I have tried many times to index a new category in my corpus, but I could not do it. I followed the next steps:

1. I used the list builder to download a list (using the filename option). Then, I opened it in Excel, and found three columns: “entity”, “frequency” and “number of distinct documents”. I included a new column with the year, next to “entity”, and saved the document as CSV. At this point, I have tried deleting the columns ” frequency ” and ” number of distinct documents”, I have saved the list in other CSV formats, tried in Mac and Windows, etc.
2. I uploaded the CSV file.
3. I started a new script using the “corpus list indexer” function. In “field” I put “filename”, I said not in “Define a custom list of entities” and yes in “Add a dictionary of equivalent strings”, where I selected the list I had uploaded (in some attempts, I put yes in both options, and selected the CSV I uploaded). Here, I also changed the name of the new process.

At this point I have the first problem. When I see the “corpus list indexer” file it has three columns with the same information, and without the year I included in the CSV list. I mean, I have the same data in “entity”, “entity label” and “forms”. So, when I try to do the next analysis, it appears an error.
I do not know what else I can do. I would appreciate your help!
Thank you very much,
Yuri
