hi
i need to select a few columns of two txt files and write it to a new file. there is one common field for both of these files.
plz help me in this
thanks in advance (4 Replies)
Hello!
I wan't to extract columns from two files and later combine them for plotting with gnuplot. If the files file1 and file2 look like:
fiile1:
a, 0.62,x
b, 0.61,x
file2:
a, 0.43,x
b, 0,49,x
The desired output is
a 0.62 0.62
b 0.61 0.49
Thank you in advance! (2 Replies)
Hi,
I want to select columns from multiple files and combine them in one file. The files are simulation-data-files with 23 columns each and about 50 rows. I now use:
cut -f 11 Sweep?wing-30?scale=0.?0?fan2?.txt | pr -3 | awk '{printf("\n%s\t%s\t%s",$1,$2,$3)}' > ../Data_Processed/output.txtI... (1 Reply)
Hi there!
I have the following problem:
I have a set of files called rates_op_yyyyddmm with the format below (which corresponds to the file rates_op_20090130)

Hi everyone,
I got a problem with merging files and hoped one of you would have an idea how to approach this issue. I tried it with awk, but didn't get far. This is what I have:
I got 40 files looking like the ones below. All have three columns but the number of rows differs (20000 to 50000).... (6 Replies)
Hi,
I have two text files that I would like to merge/join. I would like to join them if the first columns of both text files match and the second column of the first text file matches the third column of the second text file.
Example input:
First file:
1334 10 0 0 1 5.2
1334 12 0 0 1 4.5... (4 Replies)
Hi guys,
I have very basic linux experience so I need some help with a problem.
I have 3 files from which I want to extract columns based on common fields between them.
File1:
--- rs74078040 NA 51288690 T G 461652 0.99223 0.53611 3
--- rs77209296 NA 51303525 T G 461843 0.98973 0.60837 3... (10 Replies)
Hi,
I am facing issues while accomplishing below task.
We have two files Test1.txt and Test2.txt. We have to match 1st column of Test1.txt file with 2nd column of Test2.txt and then merge 2nd file with the 1st file. In the output we should select column 1 and 2 from the 1st file and column 1... (5 Replies)

discgrp
discgrp(5gv) Geometry Project Programs discgrp(5gv)NAME
discrete group file formats
SYNOPSIS
An ascii file representation of a discrete geometric group.
SUMMARY
This file format applies to a wide variety of groups encountered in topology and geometry. At the beginning of the file is the string DIS-
CGRP, in conformity with other OOGL file formats (see oogl(5)). The remainder of the file is a series of parenthesized expressions.
The file format is based on an expandable set of key markers and values. A typical entry would be
(group borromean )
where parentheses enclose the expression. The string 'group' is called the key marker. The remaining text contains a value, in this case
a character string which is the name of the group. Key markers currently recognized and their values include:
group A name for this group.
comment An arbitrary comment [maximum length 256 bytes]
[must be enclosed in double quotes]
attribute One of a several keyword identifiers including:
euclidean is a euclidean group
hyperbolic is a hyperbolic group
spherical is a spherical group
transposed the matrices are transposed
finite this is a finite group
model In the case that 'hyperbolic' is an attribute, and the dimension is
three, this keyword sets the model that is
expected for reading subsequent isometries, i.e., expects elements of
SL(2,C) if the model is upperhalfspace or conformalball and O(3,1,R) if it is
projective.
projective default
upperhalfspace
conformalball [not currently implemented]
display These values set characteristics of the the display of the discrete
group.
centercam keeps the camera centered in central dirichlet domain.
zcull removes tiles which lie behind the camera.
showcam if centercam is set, displays camgeom, if provided (see below).
dimn The dimension of the space.
ngens Number of generators.
gens List of generators.
nels Number of group elements.
els List of group elements.
wafile Word acceptor file (in DEAGL format version 2.2)
camgeom An OOGL-format geometry description to represent the observer.
geom An OOGL-format geometry description. Will replace the default Dirichlet domain computation.
String-matching of key markers and attribute values is case-insensitive.
Currently all matrices must be 4x4 real matrices. Hence the only valid dimensions are 2,3, or 4. The typical case is dimension 3 where
there are projective models for hyperbolic, euclidean, and spherical geometry. Dimension 2 groups should leave the z-coordinate unchanged.
Matrices are considered transposed if they are considered to act on column vectors as in: M.v = v'. This is the usual mathematical conven-
tion convention. So, if you use this convention you must mark your matrices as being transposed.
Group elements are specified by an optional character string followed by a list of 16 real numbers. For the case of generators, the char-
acter string represents the name of that generator. Its main use is with the automatic group software: the name used here should match that
of the generator in the word acceptor file. It should, for example, be a single character for the software to work reliably. For composite
elements, the string is the word in the generators which describes this group element.
OOGL libraries expect discrete group files to use the '.dgp' suffix.
A file which describes the group of the three dimensional torus follows:
DISCGRP
(group 3torus )
(comment " This is a test of the new discrete group library. " )
(attribute Euclidean )
(display centercam )
(enumdepth 3 ) # look at all words of length 3 or less in generators
(enumdist 10.0 ) # and which don't move the origin more than 10.0
(dimn 3 )

FILES
Example group files are to be found in the OOGL release in ${GEOM}/data/groups, where e.g., GEOM = /u/gcg/ngrap. See also discgrp(3) and
automata(1).

BUGS
For dimension 2, the code should read and write 3 x 3 matrices.
