How to load a file into the matrix form in linux platform?

Hello All,

I have recently switched to the linux platform and I have some questions.

First, I suppose I do not need anything in my windows script file (m-file) while I am compiling it in linux. Right?

Second which is extremely important to me and can save me thousands of hours:

I have a gigantic file in the following format:

 ITEM: TIMESTEP
 0
 ITEM: NUMBER OF ATOMS
 200
 ITEM: BOX BOUNDS pp pp pp
 0 23.5
 0 23.5
 0 23.5
 ITEM: ATOMS id type x y z
    1     1               4.629738099               19.15100895               8.591289203
    2     1               5.379313371               19.12269554               8.727806695
    3     1               7.531762324               13.25286645               4.981542453
    4     1               7.427444873               13.99400029               5.110889318
    5     1               21.55774217               15.43904552               5.981577486
    6     1               21.46897866               15.51226749               5.231419927
    7     1               14.99102971                3.73871179               18.17533436
    8     1                14.2887607               3.667327185               18.45545109

the file is consisting of 6000000 cycles.each cycle contains 209 lines. the first 9 lines of each cycle are exactly similar and including words, the other 200 lines are containing numbers in the matrix format you can see in the example illustrated above. The only information which i need to have is the last 4 columns of the matrix form for each cycle.

Previously, I used a fortran code to convert the original gigantic file to the following format:

1    4.62973809900       19.15100895000        8.59128920300 
1    5.37931337100       19.12269554000        8.72780669500
1    7.53176232400       13.25286645000        4.98154245300
1    7.42744487300       13.99400029000        5.11088931800
1   21.55774217000       15.43904552000        5.98157748600
1   21.46897866000       15.51226749000        5.23141992700

And then by transferring this file to my desktop where I could easily use load syntax to save the contents in a matrix form. Then I could do my calculations.

Please note that, my transferred file has 600000*200 lines and each of these lines has 4 columns. In other words I connected the cycles to eachother and removing the first 9 lines of each cycle. Is it possible to do the same thing in MATLAB? as a result, I will no longer need to first use my fortran code and then transfer the file to my desktop and load the file.

My read format in fortran is :

format(21x,f16.0,10x,f16.0,10x,f16.0)

and my write format was :

format(A1,1x,f16.11,5x,f16.11,5x,f16.11)

I do appreciate if anyone can help me with these questions. Thanks
