Reading a .dat file in to 2 different arrays
hi all, i have a data file that contains 2 columns, names and numbers. i need to read names in to a an array call names and numbers in to an array call numbers. i also have # and blank lines in my dat file and i need to skip those when i read the dat file. how do i do this? btw, my column 1 and column 2 is seperated by "TAB". i am using k shell (.ksh).
i was able to read without an issue when there was a one cloumn of data. i am not sure how to do this with 2 columns. can someone please help me?
Data file format as follows
2345th3 rghtyk
2345thh fhtene
345672 dkerjgt
#fjerflghh
er4566 djefklrgl
i would like arrays to be like this,
numbers[0]=2345th3
numbers[1]=2345thh
numbers[2]=345672
numbers[3]=er4566
names[0]=rghtyk
names[1]=fhtene
names[2]=dkerjgt
names[3]=djefklrgl

Hye all,
I would like some help with reading in a file in which the data is seperated by commas. for instance:
input.dat:

for the above case, the fn. will store the values into an array -> data as follows:
data = 1
data = 2
data = 34
data = /test

geom(1) geom(1)
NAME
geom - analyzes a molecular geometry input in Cartesian coordinates.
DESCRIPTION
The program geom reads a set of Cartesian coordinates and determines from them the bond distances (Bohr and angstrom), bond angles, tor-
sional angles, out-of-plane angles (optional), moments of inertia, and rotational constants.
FILES REQUIRED
input.dat - Input file
and one of the following:
geom.dat - geometry file
file11.dat - PSI-format geometry/gradient file
FILES GENERATED
geom.out - file containing the analysis
INPUT OPTIONS
The geom program has the following options:
-h Print help information (these options).
-aces [filename]
Read the input in an ACES output format, with each line consisting of atomic symbol, atomic number, and Cartesian coordinates (in
Bohr). The optional argument is the name of the geometry input file, which defaults to geom.dat.
-qchem [filename]
Read the input in an QCHEM output format, with each line consisting of the atom number, the atomic symbol, and Cartesian coordinates
(in Angstroms). The optional argument is the name of the geometry input file, which defaults to geom.dat.
-xyz [filename]
Read the input in an XYZ output format. The first line contains the number of atoms and the second line is a comment line. Subse-
quent lines each contain the atomic symbol and Cartesian X Y and Z coordinates (in Angstroms). The optional argument is the name of
the geometry input file, which defaults to geom.dat.
-oop Print out-of-plane angles, where the angle a-b-c-d is defined as the angle formed by the vector a-d and the plane defined by atoms
b, c, and d.
DO_OOP = boolean
Same as command-line switch -oop described above.
ISOTOPES = matrix of reals/strings
Used to specify masses to be used in the calculation of the center of mass and rotational constants. One array is provided for each
isotopomer to be calculated. The arrays can mix floating point numbers with strings which designate isotopes. If this array is not
given and file11.dat is present, then the masses will be obtained by converting the atomic numbers in file11. If masses are not
given by ISOTOPES or by file11, then no mass-related quantities will be calculated.
-g [filename]
Read Cartesian coordinates from a file other than file11.dat. If a filename is not given, the default is geom.dat. The alternative
file is assumed to be in a format similar to that of PSI's geom.dat. Since such files do not contain atomic numbers, the moments of
inertia and rotational constants are not calculated if this option is used.
READ_GEOM = boolean
This option in input.dat tells geom to read the geometry from geom.dat in the PSI geom.dat format.
-a Print parameters for all pair distances.
PRINT_ALL_DIST = boolean
Same as -a flag described above.
-d distance
Only print parameters involving pairs of atoms which are less than distance bohr apart (default value is 4.0 bohr).
PRINT_DISTANCE = value
Same as -d flag described above.
-angstrom
The input coordinates are in angstroms, not bohr.
ANGSTROM = boolean
If TRUE, the input coordinates are in angstroms instead of bohr. The default is FALSE.
The following example is for calculating the geometrical information for water with several different isotopes. The geometry is
read from geom.dat rather than from file11.dat.
geom: (
read_geom = true
isotopes = (
(O H H)
(O D D)
(O18 1.007825 1.007825)
) )
