Hello,
I have a number of tab delimited data files consists of two columns. Like that:
File1

Hi there,
I'm trying to merge two files and make a third file.
However, two of the columns need to match exactly in both files AND I want everything from both files in the output if the two columns match in that row.
First file looks like this:
chr1 10001980 T A

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)
Dear List,
I have a file of csv data which has a different line per compliance check per host. I do not want any omissions from this csv data file which looks like this:

Hi,
i have 2 files , the data i need to match is in masterfile and i need to pull out column 3 from master if column 1 and 2 match and output entire row to new file
I have tried with join and awk and i keep getting blank outputs or same file
is there an easier way than what i am... (4 Replies)

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
