`-1 is out of range` error in run_tests.pro

i have built FIDASIM successfully, and it compiled correctly.

[jiangdi@login110 FIDASIM]$ ./fidasim

Version: v1.2.4-dirty

FIDASIM is released as open source code under the MIT Licence.
For more information visit http://d3denergetic.github.io/FIDASIM/

usage: ./fidasim namelist_file [num_threads]

But when i run the test case within IDL,something like that come out,what's the problem?

IDL> run_tests,"/nfs_share/users/jiangdi/Desktop/Taowei/fida_output"
% Compiled module: RUN_TESTS.
% Compiled module: GET_FIDASIM_DIR.

The problem is that run_tests uses some features that were introduced in IDL v8.0 which was released in the year ~2010. Specifically, the ability to index an array with a negative integer as a means of indexing from the end of the array. The line that is giving you problems is

if run[-1] eq 1 then run[*]=1

The preferred way to fix this is updating your IDL version (the latest is v8.7). If that is not possible, you can replace the line in run_tests.pro with

if run[n_elements(run)-1] eq 1 then run[*]=1

Alternatively, if you are feeling adventurous, you could use the development version of FIDASIM which has a Python version of run_tests.pro

Thank you very much. i can't update the IDL because it's installed on the server.i try to fix all errors by modifying the code,but there remain some errors i can't fix. The pre-processing completed with several errors.

How can i fix it?

The error you are referring to does not affect the output of the run_tests procedure. If the code below executes, you can feel rest assured that you executed the procedure correctly. We are working on removing this small error/warning message and others.

SUCCESS: FIDASIM pre-processing completed

Since nothing is actually wrong, EFIT errors aside, I am closing this issue.
