Step 1: Latest code?

[ ] This issue is present in the most recent code (i.e. after running git pull this is still a problem).

Step 2: Describe your environment

irfu-matlab branch (e.g. master, devel): ____master
Matlab version used (e.g. Matlab R2020b): ____R2018b
Operating system (e.g. Windows 10, Mac OS X 10.15.6, Linux Ubuntu 20.04): ____Windows 10
[ ] A 64-bit installation of Matlab was used. yes

Step 3: Describe the problem

While running "Example_MMS_particle_DEFlux.m", I am getting an error message for line no. 14.

Dot indexing is not supported for variables of this type.

Error in mms.get_data/get_ts (line 946) theta = dist.DEPEND_2.data;

Error in mms.get_data (line 525) res = get_ts('skymap');

Error in c_eval (line 48) for cl_id=sc_list_1, evalin('caller', irf_ssub(ev_str, cl_id)), end

The line no. 13 which is for electron distribution is executed smoothly, whereas, line no. 14 which is for ion distribution giving an error message.

I will be pleased enough to get your early suggestions and help.

Thank you.

Dear @Krushna-100,

may I ask you ti confirm that you have downloaded the corresponding mms3_fpi_brst_l2_dis-dist files and copied them to their corresponding folders (mms3\fpi\brst\l2\dis-dist\2015\10\30\) along with the mms3_fpi_brst_l2_des-dist files to their folders (mms3\fpi\brst\l2\des-dist\2015\10\30\)?

The error you experienced Dot indexing is not supported for variables of this type. can typically be seen if trying the corresponding line theta = dist.DEPEND_2.data; on an empty dist variable, meaning it failed to identify and load the files FPI ion distribution files.

With best regards,

Thomas Nilsson

Dear Nilsson,

Thank you very much for your quick reply. Although I added initially the "mms3_fpi_brst_l2_des-dist" file to the folder, however, the "mms3_fpi_brst_l2_dis-dist" file was missing. After adding the latter file, it worked perfectly fine.

Thank you so much once again for your valuable suggestion.

With best regards, Krushna
