Seismic Unix Installation in Ubuntu

Download the installation file from CWP website:  click here to download.

After downloading the file, extract the file, you will get a folder called "src"

Now, Make a Directory, where you want to install Seismic Unix...in my case, i am creating "cwp" directory in home directory:

mkdir cwp

Now move the "src" folder in "cwp" directory:  copy "src" and paste it in "cwp".

mv src /cwp/              if src is in your home directory

Go to src/cwp directory:

cd cwp/src

Then type the following command one by one in terminal: Make sure you are in "src" directory.

echo "export CWPROOT=~/cwp" >> ~/.bashrc

echo "export PATH=$PATH:~/cwp/bin" >> ~/.bashrc

source ~/.bashrc

make install 

sudo apt-get install libx11-dev

sudo apt-get install libxt-dev

make xtinstall  

 Now Seismic Unix is installed in your system if you don't get any error up to now. To check it, run this:

suplane | suximage title="My first test" &

 For any query, please, write a comment..........thank you!

MATLAB Installation in Linux/Ubuntu:

Step 1: Download the installation file and Extract the file (Lets Extracted Folder = MATLAB)
Step 2: Go to MATLAB Folder using terminal: eg: suppose our extracted folder "MATLAB" is in  Downloads Directory, the use this command: cd Downloads/MATLAB

Step 3: Run this to install: sudo ./install

Step 4: Follow the instructions, Matlab will be install in /usr/local/MATLAB/R2012a (directory by default).

Step 5: How to launch Matlab: 
Method A:

Go to home directory and export the PATH is .bashrc file as:

gedit .bashrc &

export PATH=$PATH:/usr/local/MATLAB/R2012a/bin

source ~/.bashrc

Method B:

Try navigating to bin folder in your Matlab installation directory:

cd /usr/local/MATLAB/R2012a/bin

Then execute Matlab from there:

./matlab

if that worked for you, you can create alias:

cd /usr/local/bin/
sudo ln -s /usr/local/MATLAB/R2012a/bin/matlab matlab

This trick will allow you to launch matlab from any directory, as you were trying to do. Note that you should use sudo for the last command, since it creates alias globally, for all users.

If you are not in sudoers list (i.e. you cannot use sudo command), you can create alias locally. To do that, open .bashrc file, which is in your home directory:

gedit ~/.bashrc

Add the following line to the end of that file:

alias matlab="/usr/local/MATLAB/R2012a/bin/matlab"

Finally, reopen your terminal, or type source ~/.bashrc and execute this command.
