Hello,

I have installed Orthanc on a Win7 PC today. It's working great over my home PACS. I could send my US studies to it from my Osirix. 

Now I'm trying to make the lua script work, but I couldn't.

I Hope if anyone can help me.  The major problem is that I don't know how to check where the error is.


PART of CONFIG FILE:

// List of paths to the custom Lua scripts that are to be loaded
// into this instance of Orthanc
"LuaScripts" : ["C:\\Orthanc\\Script\\writetodisk.lua" ],
 
LUA CONTENT:

TARGET = 'C:\\ExamesUS'

function ToAscii(s)
   return s:gsub('[^a-zA-Z0-9-/-: ]', '_')
end

function OnStableSeries(seriesId, tags, metadata)
   print('This series is now stable, writing its instances on the disk: ' .. seriesId)

   local instances = ParseJson(RestApiGet('/series/' .. seriesId)) ['Instances']
   local patient = ParseJson(RestApiGet('/series/' .. seriesId .. '/patient')) ['MainDicomTags']
   local study = ParseJson(RestApiGet('/series/' .. seriesId .. '/study')) ['MainDicomTags']
   local series = ParseJson(RestApiGet('/series/' .. seriesId)) ['MainDicomTags']

   for i, instance in pairs(instances) do
      local path = ToAscii(TARGET .. '/' .. 
                              patient['PatientID'] .. ' - ' .. patient['PatientName'] .. '/' ..
                              study['StudyDate'] .. ' - ' .. study['StudyDescription'] .. '/' ..
                              series['SeriesDescription'])

      -- Retrieve the DICOM file from Orthanc
      local dicom = RestApiGet('/instances/' .. instance .. '/file')

      -- Create the subdirectory (CAUTION: For Linux demo only, this is insecure!)
      os.execute('mkdir -p "' .. path .. '"')

      -- Write to the file
      local target = assert(io.open(path .. '/' .. instance .. '.dcm', 'wb'))
      target:write(dicom)
      target:close()
   end
end

Hello,

According to the logs you provided, your Lua file is not loaded by Orthanc.

You have visibly not modified the proper configuration file.

HTH,

Hi, 
Thanks for the reply.

I have replaced the config file and now it’s working. 

The script was creating a “- p” folder and I deleted this part also. 

Now everything is doing OK.

Sebastian, do you know if Orthanc can generate print files ?
Other solutions like “k-pacs” and “microdicom” can export to windows printers. 
It’s possible ?

Thanks
