ERROR: Gene KO GO species map file is empty


My ExpressAnalyst workflow crashes seconds after launching; the log file says: ‘ERROR: Gene KO GO species map file is empty’.

The files seem to load normally (powershell) and are checked to be good to go. I am working with a non-model nematode species, and downloaded the ‘nematodes’ database with 6 spp (for Seq2Fun). I used the default parameters for read mapping and quantification. I tried to modify the nb. of allowed AA mismatches, etc, but the result remains this error message:

ERROR: Gene KO GO species map file is empty.

Does anyone know where the problem is?


Hi Lulu,

We have figured out the reason of this issue. Please put the database files directly into the DATABASE folder without any subdirectories.
