When I run mageck nest with the command below, I get the error that the control sgRNAs cannot be found. Does anyone know the correct format to pass the controls to mageck nest?

Command I'm running:

mageck_nest nest -k count.txt \
  -d designmatrix4.txt \
  --norm-method control \
  -e controls.txt \
  -n nest

The only time it can find the controls is if, instead of passing a file for -e, I pass a single gene name:

mageck_nest nest -k count.txt \
  -d designmatrix4.txt \
  --norm-method control \
  -e TERGENIC76054 \
  -n nest

(Which then subsequently throws a long load of python errors, and isn't the analysis I want anyway).

Any format for controls.txt that I can think of doesn't seem to work (and the demo list of controls doesn't work).

Any suggestions appreciated!
