hi juan,
*ccfopr is relevant only to relccsd.
one remark: please keep in mind that, as mentioned in the *exacc section, the code will store all data in memory and not use point group symmetry, as it is geared towards tackling larger systems.
so, in terms of usage, if the species you want to investigate have high (point group) symmetry, you should perhaps investigate which code (relccsd or exacorr) will give you results faster.
but you probably don't want to run both codes, as you have now in the sample input, if you want exactly the same functionality in both cases, as you should get the same result..
best,
andre
