CSI.tar contains a directory CSI with the files
        Nucleus.ure     - random coil shifts
        Nucleus_seq.ure - sequence correction factors.
Both contain general in formation in the first four lines:
line 1: reference
line 2: standard, ppm value of standard, temperature (K), pH,
concentration of cosolvents (this field is only used if a concentration
dependent correction is used in the NMRView script).
line 3: remarks
line 4: names for the columns with the data
>From line five on the files contain the actual data. 
Columns in the shift files: amino acid (singel letter code), shift
(ppm), cut-off helix (ppm), cut-off sheet (ppm), correction for
temperature dependence (ppb, only used for HN), correction for cosolvent
concentration in % (not used with this data set), correction for molar
cosolvent concentration (not used with this data set), correction for
deuterium effects (currently not used).
Columns in the sequence correction files: amino acid (singel letter
code), A, B, C, and D (four columns for the correction factors. In A and
D contain data only in a few cases because in general such long range
effects should not be treated, as discussed in the paper).
