Dear Aladin/Hipsgen user,

The MOC and MAP action of Hipsgen only required the "out" parameter for 
knowing the target HiPS directory. You can specify the "in" directory 
(original images), but the "out" must pointed to the target HiPS.
So your command should be:
java -Xmx32g -jar ~/software/Aladin/Aladin.jar -hipsgen verbose=3 
out=Swift_xrt_int_all2 mocOrder=8 MOC

Same for MAP

Best regards
Pierre Fernique
