Opening and read .dat file double format
type: item
description: Hi everyone I have a .dat file double and is 5000 by 8039. I'm using the file in Matlab and I want to try to open it in IDL. So I know it is very basic question but I'm new in IDL and I want to start using it. After I open the file, I want to read like the value of (1,1) Thanks in advance

After I open the file, I want to read like the value of (1,1) What format is the data in? ASCII? Binary? Matlab format? It makes a difference.

Thanks Craig My data is Binary double format and I used the following because I want to extact the image to see as I'm doing in Matlab template = BINARY_TEMPLATE('C:\Users\asus\Desktop\Metasensing\IDL_PROJE CTS\20151021115853_11_SAR_CPLX_0_pres_8.dat') Result = READ_BINARY('C:\Users\asus\Desktop\Metasensing\IDL_PROJECTS\ 20151021115853_11_SAR_CPLX_0_pres_8.dat', DATA_DIMS = [4999, 8038]) im = IMAGE(Result) end But I got an image meaning nothing to me only white and black image Am I doing the right way or there are other ways to see the image Thanks
