Piper file for Drug mention Annotation

[Narayan Bhat <bn...@manuhsolutions.com>]

Hi

My piper file had the following analysis engines for drug mention
annotation purpose however on executing the piper file through
builder.run() I do not see any annotations related to drug annotation like
medication strength, frequency, frequency modifier types being added to XMI
output.

Is flow control required here like in Aggregate engines?

PiperFile name: UmlsLookupPipeline.piper

Text file content: Administration of Prilosac ( omeprazole ) 20 mg twice
daily for 4 days
