Talend workflow for calculated field

I want to 1)read multiple gzip files from a path, 2)un-archive and 3)create a calculated field. So far i have been successful in doing 1 and 2. For 3, i thought that tMap will do the needful, however don't know why i am unable to connect the un-archive component with tMap.

Hi,
tFileUnarchive will unarchive file(s) you have to read (for example with tFileInputDelimited) to push the data into the tMap.
If multiple files in the archive, use a tFileList to iterate over the desired extraced files.

from tfileUnarchieve, for connecting with tFileInputDelimited, 1) should i iterate or do OnComponentOk? 2) what should i use as 'File name/Stream'?

onSubJobOK - tFileList - tFileInputDelimited((String)globalMap.get("tFileList_1_CURRENT_FILEPATH"))

Can you elaborate entire process? I tried 
tFileList ->(iterate) -> tFileUnarchive -> (onComponentOk as onSubjOk) -> tFileInputDelimited
I inserted ((String)globalMap.get("tFileList_1_CURRENT_FILEPATH")) in the file name/stream box. The problem is when i click on edit schema it does not show me anything.
