I want Orthanc to auto route dicom files to a specific directory in my computer. I don’t know what parameter I have to put in the quotes written sample below so that the files will be routed to my desired directory:

function OnStoredInstance(instanceId, tags, metadata)  
SendToModality(instanceId, ‘sample’)  
end

Have tried to put the path to the directory but nothing is working. I am only reiving the error that it Couldn’t read data from file “route\_dicoms.lua”.

How can I solve this?

That script is used to auto route to another DICOM modality. You would need to use something like the WriteToDisk.lua which is included in the Orthanc source code.
