Error with regionprops, Expected input number 1, PROPERTIES, to match one of these values:

Hello, i'm trying to get the MinorAxisLength from a serie of images via regionprops function with a for loop and i'm getting a bunch of errors that i dont know how to solve.

Section of my code:

for z = 1: 4

Image_stats(z).Bloque3 = regionprops (Image_thr(z).Bloque2, 'MinorAxisLenght');

end

This are the errors i get from Matlab:

Error using regionprops>getPropsFromInput (line 1447)

Expected input number 1, PROPERTIES, to match one of these values:

'LabelName', 'Area', ...

The input, 'MinorAxisLenght', did not match any of the valid values.

Error in regionprops>ParseInputs (line 1412)

reqStats = getPropsFromInput(startIdxForProp, ...

Error in regionprops (line 248)

[I,requestedStats,officialStats] = ParseInputs(imageSize, argOffset, args{:});

Error in script_detectar_desgaste (line 53)

Image_stats(z).Bloque3 = regionprops (Image_thr(z).Bloque2, 'MinorAxisLenght');

I have to say that before trying to get the values this way, i used the following code and worked, but i wanted to make it more efficient with a loop:

Image_stats1 = regionprops (Image_thr1, 'MinorAxisLength');

Image_stats2 = regionprops (Image_thr2, 'MinorAxisLength');

Image_stats3 = regionprops (Image_thr3, 'MinorAxisLength');

Image_stats4 = regionprops (Image_thr4, 'MinorAxisLength');

Thanks for reading and sorry if my english is a little bad. Grettings from Spain ;)

Already answered my self, sorry to to bother you guys, MinorAxisLength was spelled wrong hahahha

The little errors are the ones that kill me :)
