-(A) no, this is normal, this is just the output of FROG, showing that everything is ok.

+(Q) Delphes complains that data/DataCardDet.dat is not found.
+(A) In more recent version of the code (>1.4beta) the default names have been changed to DetectorCard.dat.
+ Similarly, trigger cards are now called TriggerCard.dat
+
+
+(Q) May I run the convertor stage independently before running Delphes?
+(A) Yes, you can convert your generator-level input files, by running the 'Convertors_Only' executable:
+        me@mylaptop:~$ ./Convertors_Only
+        Usage: ./Convertors_Only input_file output_file
+        input_list - list of files in Ntpl, StdHep of LHEF format,
+        output_file - output file.
+        me@mylaptop:~$ ./Convertors_Only TEST.list converted.root       
+
+
+(Q) I did not create a LHCO output file when I ran Delphes (FLAG_lhco=0). Can I do this on my ROOT output file?
+(A) The LHCO output file can be easily created out-of your Delphes ROOT output file, by running the 'LHCO_Only' executable:
+        me@mylaptop:~$ ./LHCO_Only
+        Usage: ./LHCO_Only input_file [runlog_file]
+        input_file - file in Delphes root format,
+        [runlog_file] - the corresponding log file (optional)
+        me@mylaptop:~$ ./LHCO_Only test.root
+
+(Q) I did not run the triggers when I ran Delphes (FLAG_trigger=0). Can I reprocess this on my output file?
+(A) There is no problem to re-run the trigger on a Delphes output-file. Just run the 'Trigger_Only' executable:
+        me@mylaptop:~$ ./Trigger_Only
+        Usage: ./Trigger_Only input_file output_file [detector_card] [trigger_card]
+        input_file - file in Delphe root format,
+        trigger_card - Datacard containing the trigger algorithms (optional)
+        me@mylaptop:~$ ./Trigger_Only test_without_trigger.root test_with_trigger.root data/mydetector.dat data/mytrigger.dat
