Getting started

[Thomas Eden]

Hello,

I just downloaded the standalone version of CHIANTI, and I tried running the use_chianti.pro script like so from the IDLDE:

IDL> use_chianti, '/'/Users/thed4993/data1/chianti/'

but it bombs at line 130 as it doesn't know what dir_exist(XUVTOP) means. Is there something I need to do environmentally to make this script aware of such a function?

Thanks,

Tom Eden

Hi Tom,

one of the first things you need to do is set the environmental variable XUVTOP to point to the top of the database

.

check out the user guides on chiantdatabase.org

Thanks for the reply, Ken. I set the environmental variable XUVTOP

IDL> setenv, 'XUVTOP=/Users/thed4993/data1/chianti/'

and I checked to see if it was successful:

IDL> PRINT, 'Environment variable: ', getenv('XUVTOP')

and it was, so, I then ran

IDL> use_chianti, '/Users/thed4993/data1/chianti/'

And it still bombs at line 130. Here's the error:

% Variable is undefined: DIR_EXIST.
% Execution halted at: USE_CHIANTI       130 /Users/thed4993/data1/chianti/setup/use_chianti.pro
%                      $MAIN$

Thanks for your help,

Tom

Hi Tom,

 

Thanks for using CHIANTI. There’s an error in how you called use_chianti, which might be the problem. It should have been:

 

use_chianti, '/Users/thed4993/data1/chianti/'

 

Also, please try:

 

IDL> which,’dir_exist’

 

as this will indicate if the CHIANTI software is on your IDL path. For example, I get

 

IDL> which,'dir_exist'

/Users/pryoung/ssw/gen/idl/system/dir_exist.pro

 

If dir_exist is not found, then please check the instructions for setting up the standalone version. You need to put the following lines in your IDL_STARTUP file:

 

!PATH = '+/data1/chianti/idl:'+!PATH

!PATH = EXPAND_PATH(!PATH)

use_chianti, '/data1/chianti/dbase'

 

(where you should insert your own CHIANTI path).

 

Hope this helps,

 

Peter
