IDL, short for Interactive Data Language, is an interactive shell based data analysis programming language. Used vastly in medical imaging, it can quickly create visualizations and graphs of large data sets in a few easy steps due to its vector nature. FORTRAN users would be familiar with the IDL syntax. IDL is not to be confused with Java IDL or Microsoft IDL.
Basic IDL Usage
To start IDL, open a terminal window and type
idl. This will start the interactive shell.
Variables in IDL
To initialize variables in IDL, type:
<variable_name> = <variable_value>
x = 3
and hit Enter/Return
To print the variable, type
Arrays in IDL
To make arrays in IDL, follow the format below:
<array_name> = [val1, val2, val3,...,valx]
myarray = [1,2,3,4]
We have a limited number of IDL Licenses available, which are provided on a first-come-first-serve basis. As a consequence, availability of IDL on your VM is not always guaranteed once a VM request is submitted. Please consult with us before requesting IDL.
