o.run() not working when using nested loop

[pzs6]

Hi, i wish to use o.run() for a bunch of different end_times for diferent readers, thats why I decided to use a nester for loop. But I receive the following error 'opendrift.errors.WrongMode: Cannot call this function in this mode: Mode.Result, only in: [<Mode.Run: 3>]: None'
The loop has more less this syntax:
`for i ...:
for t in range(len(times_to_plot)):
plot_filename = f"{names[i]}_{timestamp[t]}.png"
o.run(end_time=times_to_plot[t],time_step=dt.timedelta(days=1))
o.plot(linecolor='origin_marker',
fast=False,
show_elements=False,
filename=plot_filename )´
Has anyone faced this same issue or knows a way to fix this?
Thanks in advance.

Hi,
The error message is not clear, but you have to do operations in this order:

• create object
• set config
• add readers
• run
• analysis/plot

It is not clear from your sample code which order is violated, so this is probably in the part you left out.
