Extract part of filepath and using like legendname

Hello,

I have paths like this:

FilePath =    '/home/user/workspace/QT/Software_2.0_QT/IO/Motor_Set_1/AKG_C1000S/Distance_0.5m/Scenario_M1/001_m1_60_const_20200611_200515/SNR_F1/'

and I need to save (in a loop)

Save_path{k} = 'Motor_Set_1/AKG_C1000S/Distance_0.5m/Scenario_M1/001_m1_60_const_20200611_200515/'

or maybe I can set it also shorter (for a plot legend)!?

Save_path{k} = 'MS1/AKG/0.5m/M1/001/'

?

Variables are:

Motor_Set_1, Motor_Set_2, Motor_Set_3

AKG_C1000S, SONY_D50

Distance_0.5m, Distance_2m

Scenario_M1, Scenario_M2, Scenario_M4

001_m1_..., 002_m1_m2..., ..., 030_m4_m3...

How can I cut it?

Thank you!

Make sure all slashes are forward shashes

FilePath = strrep(FilePath, '\','/');

Replace any double shashes with single slashes

strrep(FilePath, '//','/')

Find the position of the slashes

slashIdx = strfind(FilePath, '/'); 

Choose which segments of the path you want to extract (here I chose segment 10 to 13)

pathSegment = FilePath(slashIdx(10)+1:slashIdx(13)-1) 

The +1 and -1 remove the slash from the beginning and end of the segment.

You could also use regular expressions or some of the other string search functions if you want to search for a specific starting and ending directory.
