Here it is (just in case you really did not get it): From: "M.A. Martinez" <address@hidden> Date: Fri, 04 May 2001 17:16:36 +0000 Organization: inm.es To: address@hidden Subject: Re: McIDAS and Matlab Dear Tom: I have made in PV-WAVE but in Matlab must be similar The easy form is to use the McIDAS AXFORM command. With the AXFORM command you make one binary file with only the matrix data, and you can select the unit, and the format (1 byte int, 2 byte, ascii or bin etc). The dimensions and type of data are explained in the .HDR See the help of the AXFORM for more details. Once you have produces the AXFORM in matlab you allocate a matrix the same kind and dimension of the data, open the file and read it. Eg. your AREA0123 is 500 line and 800 element AXFORM 123 goes_stt in matlab data=fltarr(500,800) openru,unit,filename='$HOME/mcidas/data/goes_stt readu,unit,data You can also made directly one reader easily. Making something like this: open directly the area file, create one header+nav+cal long integer array, read the header with the binary utility, create the integer or byte matrix data, read the matrix.
