install xdna on linux

[sima]

hi
I have a windows/linux platforms
I want to install x3dna on my linux .but Nothing happens when I use this command
export X3DNA='/home/sima/x3dna-v2.4'
  export PATH='/home/sima/x3dna-v2.4/bin':$PATH

sima@HP:~/x3dna-v2.4/bin$ export X3DNA='/home/sima/x3dna-v2.4'
sima@HP:~/x3dna-v2.4/bin$ export PATH='/home/sima/x3dna-v2.4/bin':$PATH
sima@HP:~/x3dna-v2.4/bin$ source ~/.bashrc


I didn't understand the text below before executing the commands
for your 'bash' shell, add the following into ~/.bashrc:

In your current settings, what happens when you run: find_pair -h?

Change to the directory when 3DNA is installed, then type: pwd. What is the result?

What is the output of: echo $SHELL

It executes when I run the following command in the terminal I opened for installation,
sima@HP:~/x3dna-v2.4/bin$ pwd
/home/sima/x3dna-v2.4/bin
sima@HP:~/x3dna-v2.4/bin$ ./x3dna_setup
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
To install X3DNA, do as follows:
  (0) download the 3DNA distribution for your operating system from URL
          http://x3dna.org/
  (1) tar pzxvf x3dna-v2.4-linux-64bit.tar.gz
          # here for the 3DNA v2.4 distribution on 64-bit Linux
  (2) cd x3dna-v2.4/bin
  (3) ./x3dna_setup
          to run X3DNA, you first need to do two things:
              o set up the X3DNA environment variable
              o add $X3DNA/bin to your command search path
          for your 'bash' shell, add the following into ~/.bashrc:
          --------------------------------------------------------------
              export X3DNA='/home/sima/x3dna-v2.4'
              export PATH='/home/sima/x3dna-v2.4/bin':$PATH
          --------------------------------------------------------------
          and then run: source ~/.bashrc
  (4) to verify your installation, type: ./find_pair -h
          you should see some command-line help message

NAME
        find_pair - locate base-pairs and helical regions
SYNOPSIS
        find_pair [OPTION] PDBFILE OUTFILE
DESCRIPTION
        locate base-pairs and helical regions given a PDB data file. Its
        output can be directly fed into 'analyze', 'cehs' and Lavery's
        Curves+ program.
        -s, -1  treat the whole structure as a continuous single helix.
                Useful for getting all backbone torsion angles
        -c      get Curves input for a duplex
        -c+     get input for Curves+ (duplex, ATOM records only)
        -d      generate a separate output file for each helical region
        -p      find all base-pairs and higher-order base associations
        -a      read in only the ATOM records, ignoring HETATM records
        -z      more detailed base-pairing information in the output
        -h      this help message (any non-recognized options will do)
INPUT
        PDB data file
        One-letter options can be in either case, any order, or combined
EXAMPLES
        find_pair sample.pdb sample.inp
        find_pair -p sample.pdb allbp_list
        find_pair -c+ sample.pdb sample_c+.inp
                  [then run: Cur+ < sample_c+.inp]
OUTPUT
        base-pair listing for input to analyze, cehs and Curves
        bestpairs.pdb, hel_regions.pdb, col_chains.scr, col_helices.scr
        allpairs.pdb, multiplets.pdb, mulbp.inp
SEE ALSO
        analyze, cehs, anyhelix, ex_str, stack2img

sima@HP:~/x3dna-v2.4/bin$ echo $SHELL
/bin/bash

but when I close the terminal I can't call the software.
sima@HP:~$ ./find_pair -h
bash: ./find_pair: No such file or directory
sima@HP:~$ cd x3dna-v2.4/bin
sima@HP:~/x3dna-v2.4/bin$ ./find_pair -h
Please set the X3DNA environment variable
Run 'x3dna_setup', and visit http://forum.x3dna.org/ for more info.

You need to add the two lines:

Code: [Select]

export X3DNA='/home/sima/x3dna-v2.4'
export PATH='/home/sima/x3dna-v2.4/bin':$PATH
into your ~/.bashrc file so that you can access 3DNA commands each time you open a new terminal window.

Or, you can place the two lines into a file, and then source that file each time you open a new terminal window.
