I am try to achieve automatic deletion of studies after a certain period of time using Lua scripting in Orthanc, but facing some issue.
I have created a created a Lua delete_old_studies.lua and placed it in Orthanc configuration directory.
I have Lua installed on your Windows system as well.
On manually running this lua script I am getting this following message.
C:\Program Files\Orthanc Server\Configuration>lua delete_old_studies.lua
lua: delete_old_studies.lua:8: attempt to index global ‘DICOMExplorer’ (a nil value)
stack traceback:
delete_old_studies.lua:8: in main chunk
[C]: ?
C:\Program Files\Orthanc Server\Configuration>
My delete_old_studies.lua is as follows:-
– the retention period in days
local retentionPeriod = 100
– Calculate the threshold date (current date - retention period)
local thresholdDate = os.date(“%Y-%m-%d”, os.time() - (retentionPeriod * 8640000))
– Get a list of all studies
local studies = DICOMExplorer.Studies()
– Iterate through the studies and delete those older than the threshold date
for studyId, study in pairs(studies) do
local studyDate = study[‘StudyDate’]
if studyDate < thresholdDate then
DICOMExplorer.DeleteStudy(studyId)
end
end
Please help me solving this issue.
