Hello Teresa, I need to disagree with Graeme over the idea that ccp4i 'hides' what is happening. If you care to you can see all the gorey details of command files, log files etc.. You can run the programs one step at a time and with various modes with ccp4i and iMosflm and learn something of what is going on at each stage but the gui layer at least gives you a much quicker user-friendly way to control them rather than going back to prehistoric scripts. On the other hand pipelines such as xia2 will usually do the job and save you much time.
