Can't run headless script with Dataset as input parameter

[hadim]

Steps to reproduce :

• Create a small script :

# @Dataset data
# @Integer var
# @ImageJ ij

s = ij.op().run("stats.mean", data)
print(s)

print(var)

• Call it with fiji --headless --ij2 --console --run script.py "data='/home/hadim/FakeTracks.tif'"

• Got the following error :

[ERROR] For input data: incompatible object java.lang.String for type net.imagej.Dataset
