nifti1_test - NIfTI file conversion
SYNOPSIS
nifti1_test [-n2|-n1|-na|-a2] infile [prefix]
DESCRIPTION
Converts NIfTI files from and to ANALYZE 7.5 format, compressed or uncompressed NIfTI files (pair or single file). Additionally one can
convert NIfTI headers into ASCII format for convenient manipulation of header data.
If prefix is given, then the options mean:
-a2 ==> write an ANALYZE 7.5 file pair: prefix.hdr/prefix.img
-n2 ==> write a NIFTI-1 file pair: prefix.hdr/prefix.img
-n1 ==> write a NIFTI-1 single file: prefix.nii
-na ==> write a NIFTI-1 ASCII+binary file: prefix.nia
-za2 => write an ANALYZE 7.5 file pair:
prefix.hdr.gz/prefix.img.gz
-zn2 => write a NIFTI-1 file pair: prefix.hdr.gz/prefix.img.gz
-zn1 => write a NIFTI-1 single file: prefix.nii.gz
-zna => write a NIFTI-1 ASCII+binary file: prefix.nia.gz
The default is '-n1'.
If prefix is not given, then the header info from infile file is printed to stdout.
Please note that the '.nia' format is NOT part of the NIFTI-1 specification, but is provided mostly for ease of visualization (e.g., you
can edit a .nia file and change some header fields, then rewrite it as .nii)

NIFTI_STATS(1) User Commands NIFTI_STATS(1)NAME
nifti_stats - compute NIfTI statistical functions
SYNOPSIS
nifti_stats [-q|-d|-1|-z] value CODE [p1 p2 p3]
DESCRIPTION
nifti_stats supports several distributions (normal, uniform, logistic, chi, etc.) and calculates density or cummulative distribution func-
tion (and many more). Values are printed to stdout and can be piped to other tools.
value can be a single number or in the form bot:top:step.
default ==> output p = Prob(statistic < val).
-q ==> output is 1-p.
-d ==> output is density.
-1 ==> output is x such that Prob(statistic < x) = val.
-z ==> output is z such that Normal cdf(z) = p(val).
-h ==> output is z such that 1/2-Normal cdf(z) = p(val).
Allowable CODEs:
CORREL, TTEST, FTEST, ZSCORE, CHISQ, BETA, BINOM, GAMMA, POISSON, NORMAL, FTEST_NONC, CHISQ_NONC, LOGISTIC, LAPLACE, UNIFORM, TTEST_NONC,
WEIBULL, CHI, INVGAUSS, EXTVAL, PVAL, LOGPVAL and LOG10PVAL
Following CODE are distributional parameters, as needed.
Results are written to stdout, 1 number per output line.
EXAMPLE
Piping output into AFNI program 1dplot:
nifti_stats -d 0:4:.001 INVGAUSS 1 3 | 1dplot -dx 0.001 -stdin

../prefix.3
etc.
So, I would create a file and chmod it executable. But I dont know how to pass a variable to a script. I would like to write something like

I have a file:

I just want to get the number, not the prefix "chromosomeX", so I want to remove all the prefix ahead of the numbers. How can I do that?? Thanks!!! (PS: give me some very simple command so that I can understand... (4 Replies)

I need to rename each dti_FA.nii.gz file according to the name of the folder it resides in. For example, the file ... (3 Replies)
Hi,
I am entirely new to Unix, need your help to perform certain actions in unix:
