I was going through several other post and came to know that recent version of dcraw doesn't support "-o".

Is there a way to use same version of dcraw and implement this ?

No..not capital O :

Unknown option "-O".
convert: delegate failed `/opt/local/bin/dcraw -6 -w -O "%u.ppm" "%i"' @ error/delegate.c/InvokeDelegate/1065.

Thanks for pointing it out !

Thanks for reply !
