Repected Sir,
I am trying to run the irf code-named "Example_MMS_combined_irf_plot_and_subplot" and it is not able to read the data properly. The data set has been properly placed in their respective folders.
The error coming is:
Unable to resolve the name 'desDist1.tlim'.
Error in c_eval (line 48)
for cl_id=sc_list_1, evalin('caller', irf_ssub(ev_str, cl_id)), end
Error in untitled4 (line 14)
c_eval('times = desDist?.tlim(tint).time;',ic)

Thanks in Advance!
