hai Dhaval,<br><br>Please check your eof installation properly. In grads type 'q udft', then it will give the list of user defined functions on it. If it is not the problem, then check for the library file which they have provided. We have already posted the detailed step by step installation procedure for installing eof in linux. i am posting it again<br>
<br>*************************************************************************************************************<br><pre>if you are using linux 32bit OS<br><br>download PC(i386) Linux (32bit) from<br><a href="http://www.atmos.ucla.edu/%7Emunnich/Grads/EOF/">http://www.atmos.ucla.edu/~munnich/Grads/EOF/</a><br>
<br>open teminal then gedit .bashrc (your bash file)<br><br>your gradspath(where grads is installed) may be (eg: /home/alice/grads )<br><br><br>export GRADS="/home/your_home/grads"<br>export GADDIR="/home/your_home/grads/data"<br>
export GASCRP="/home/your_home/grads/lib"<br>PATH=${PATH}:$GRADS/bin<br><br>put the following line<br><br>export GAUDFT="/home/your_home/grads/udft.txt"<br><br>then it will become<br><br>export GRADS="/home/your_home/grads"<br>
export GADDIR="/home/your_home/grads/data"<br>export GASCRP="/home/your_home/grads/lib"<br>export GAUDFT="/home/your_home/grads/udft.txt"<br>PATH=${PATH}:$GRADS/bin<br><br>before the last line ( that is PATH=${PATH}:$GRADS/bin)<br>
<br>save and exit bashrc<br><br>then copy the eofudf file from the extracted directory to your grads folder.<br><br>then create a blank file called udft.txt inside your grads folder. then add<br>the following lines to it<br>
<br>eofudf 2 6 expr value value value value char<br>sequential<br>/your/path/to/eofudf <-- Your path to the eofudf executable<br><a href="http://eofudf.in">eofudf.in</a><br>eofudf.out<br><br>here set the /your/path/to/eofudf as /home/your_home/grads/eofudf (where you<br>
have copied eofudf)<br>then it will become excatly in format(dont change the order)<br><br>eofudf 2 6 expr value value value value char<br>sequential<br>/home/your_home/grads/eofudf<br><a href="http://eofudf.in">eofudf.in</a><br>
eofudf.out<br><br>then as root copy the library file libcxa.so.3 to /usr/lib<br>from treminal from the extracted folder (ie: cp libcxa,s0.3 /usr/lib)<br>go to /usr/lib and change its permission with chmod (ie chmod 777 libcxa.so.3)<br>
<br>now exit from root<br><br>either open a new terminal otherwise in current terminal give command:<br>source /home/your_home/.bashrc<br><br>now open grads and open your data. then type command: q udft<br>if it is properly installed it will give somthing like<br>
<br>eofudf Args: 2 6 Exec: /home/your_home/grads/eofudf<br><br>done...........................<br><br>now set you time (eg: set t 1 20)<br><br>set your lat and lon<br><br>then type eof your_variable<br><br>it will display and create some output files as ctl and data files.<br>
