Can't import ERT field data

[AY131313]

Hi,
I am trying to conduct an ERT field data inversion using the pygimli. I design the database exactly as it is supposed to (unified format) and it is shown in some cases like lake and etc. I try importing like below:

Load your dataset

data = ert.load(r"the path\ERTfield.ohm", load=True, verbose=True)
print(data)

The issue is that the data values are not imported and I don't know why. but as the message below, parameters like a,b,m, and n are imported as the electrode positions:

Data: Sensors: 171 data: 0, nonzero entries: ['a', 'b', 'm', 'n']

I do my work in jupyter notebook environment.
I also upload the dataset I wanna import.
ERTfield2.xlsx

I have even tried using pybert.importData(), but no data is imported.

data = pb.importData(r"the path to dataset\ERTfield2.ohm", verbose=True)
print(data)

You have (as correctly read) 171 electrodes but you refer to electrodes far above this number:

#a	b	m	n	rhoa	error
297	303	298	302	49.18	1.4754
295	305	298	302	61.12	1.8336
293	307	298	302	75.74	2.2722
....

The a/b/m/n numbers are indices into the electrode list and should be between 1 and 171. As all are above 171, the number of valid data is 0.

hello again,
Thanks for providing insight into the subject.
now I have to make my electrode distances 1 to 171, how should I do it?
Also, the psedusection section resulted from the inversion process of this exact ERT field data is uploaded. they are resulted utilizing the zonedres2D software. can you suggest setting the invert function arguments to result in something like the image?

Whereas the electrodes have arbitrary (float) positions (x and y) in the upper electrode section, the ABMN of lower section only holds indices (integer) into this list, so a 185 becomes a 1 (the first electrode mentioned), the 200 a 2 and so on.

Again: those numbers are NOT distances but indices.
