Dear all,
I have a .txt file with n=400 columns, n=440,000 rows. The file looks like below:
-0.0625123454 0.03732424 -0.11293423 ...
0.15651325435 -0.1366346346 -0.28384636 ...
...
I want to change all the numbers in the file with n=3 decimal places. I don't know if it is very simple problem but I don't know how to do it. Thanks a lot for your help.
thanks,
Lin

HI guys,
I have created a script to read 1 column in a csv file and then place it in text file.
However, when i checked out the text file, it is not in a column format...
Example:
CSV file contains

bb,22
cc,33
After using awk to get first column

This is appending a column.
My question is fairly simple. I have a program generating data in a form like so:
1 20
2 22
3 23
4 12
5 43
For ever iteration I'm generating this data. I have the basic idea with cut -f 2 fileA.txt | paste -d >> FileB.txt ???? I want FileB.txt to grow, and... (4 Replies)

Lets assume I have a text file.
The text file contains multiple "#" symbols.
I want to replace all thos "#"s with a STRING using DOS/Batch
I want to add a certain TEXT to the end of each line.
How can I do this WITHOUT aid of sed, grep or anything linux related ? (1 Reply)

Hi ,
seq can be 0...128
int windex = seq / 8;
int bindex = seq % 8;

This is the part of a program to convert decimal to bitmap value of hexadecimal.

x2sys_solve
X2SYS_SOLVE(1gmt) Generic Mapping Tools X2SYS_SOLVE(1gmt)NAME
x2sys_solve - Determine systematic corrections from crossovers
SYNOPSIS
x2sys_solve -Ccolumn -TTAG -Emode [ COE_list.d ] [ -V ] [ -W ] [ -Z ] [ -bi[s|S|d|D[ncol]|c[var1/...]] ]
DESCRIPTION
x2sys_solve will use the supplied crossover information to solve for systematic corrections that can then be applied per track to improve
data quality. Several systematic corrections can be solved for using a least-squares approach. Note: Only one data column can be processed
at the time.
-T Specify the x2sys TAG which tracks the attributes of this data type.
-C Specify which data column you want to process. Needed for proper formatting of the output correction table and must match the same
option used in x2sys_list when preparing the input data.
-E The correction type you wish to model. Choose among the following functions f(p), where p are the m parameters per track that we
will fit simultaneously using a least squares approach:
c will fit f(p) = a (a constant offset); records must contain cruise ID1, ID2, COE.
d will fit f(p) = a + b * d (linear drift; d is distance; records must contain cruise ID1, ID2, d1, d2, COE.
g will fit f(p) = a + b sin(y)^2 (1980-1930 gravity correction); records must contain cruise ID1, ID2, latitude y, COE.
h will fit f(p) = a + b cos(H) + c cos(2H) + d sin(H) + e sin(2H) (magnetic heading correction); records must contain cruise ID1,
ID2, heading H, COE.
s will fit f(p) = a * z (a unit scale correction); records must contain cruise ID1, ID2, z1, z2.
t will fit f(p) = a + b * (t - t0) (linear drift; t0 is the start time of the track); records must contain cruise ID1, ID2, t1-t0,
t2-t0, COE.
OPTIONS
No space between the option flag and the associated arguments.
COE_list.d
Name of file with the required crossover columns as produced by x2sys_list. NOTE: If -bi is used then the first two columns are
expected to hold the integer track IDs; otherwise we expect those columns to hold the text string names of the two tracks.
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
-W Means that each input records has an extra column with the composite weight for each crossover record. These are used to obtain a
weighted least squares solution [no weights].
-Z For -Ed and -Et, determine the earliest time or shortest distance for each track, then use these values as the local origin for time
duration or distance calculations. The local origin is then included in the correction table [Default uses 0].
-bi Selects binary input. Append s for single precision [Default is d (double)]. Uppercase S or D will force byte-swapping. Option-
ally, append ncol, the number of columns in your binary input file if it exceeds the columns needed by the program. Or append c if
the input file is netCDF. Optionally, append var1/var2/... to specify the variables to be read.
EXAMPLES
To fit a simple bias offset to faa for all tracks under the MGD77 tag, try
x2sys_list COE_data.txt -V -TMGD77 -Cfaa -Fnc > faa_coe.txt
x2sys_solve faa_coe.txt -V -TMGD77 -Cfaa -Ec > coe_table.txt
To fit a faa linear drift with time instead, try
x2sys_list COE_data.txt -V -TMGD77 -Cfaa -FnTc > faa_coe.txt
x2sys_solve faa_coe.txt -V -TMGD77 -Cfaa -Et > coe_table.txt
To estimate heading corrections based on magnetic crossovers associated with the tag MGD77 from the file COE_data.txt, try
x2sys_list COE_data.txt -V -TMGD77 -Cmag -Fnhc > mag_coe.txt
x2sys_solve mag_coe.txt -V -TMGD77 -Cmag -Eh > coe_table.txt
To estimate unit scale corrections based on bathymetry crossovers, try
x2sys_list COE_data.txt -V -TMGD77 -Cdepth -Fnz > depth_coe.txt
x2sys_solve depth_coe.txt -V -TMGD77 -Cdepth -Es > coe_table.txt
