reader for Nissa text format correlation functions
readnissatextcf(file_basenames_to_read, smear_combs_to_read, Time,
combs_to_read, nts = Time, sym.vec = c(1), symmetrise = FALSE)Character vector of file names without the
smearing combination suffixes (such as 'll', 'ls', 'sl', 'ss')
which will be added in the reading routine accordign to what was
passed via smear_combs_to_read. An example would be
'0001/mes_contr_2pts', not the lack of the smearing suffix.
Character vector containing the smearing cominations that are to be read.
These will be attached to the file_basenames_to_read in the reading routine.
Integer, time extent of the lattice.
Data frame containing the indices of the masses and r-paramter combinations to be read as well as the name of the spin combination. For a two-point function using the second and third mass (0-indexed), the (+^dag,+) r-combination and the pseudoscalar-pseudoscalar spin combination would look as follows:
| m1_idx | m2_idx | r1_idx | r2_idx | spin_comb |
Integer, number of time slices to be read from the correlator files.
Integer or numeric vector. Specifies whether the correlator at
the given position is symmetric (+1.0) or anti-symmetric (-1.0 )
under time reflection. This is passed to symmetrise.cf. This
should be of sufficient length to cover all correlators that are
going to be read (one number per row of combs_to_read and
per entry of smear_combs_to_read)
Boolean, specifies whether averaging over backward and forward correlators should be done after the correlator has been read in.
Returns an object of class cf.
