Hi Scholi,

I have been trying to use spectra on my data (TOFion) and I received the following error

To Reproduce Snippet of code creating the error image

Please run the following and attach the result to your issue `Python 3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 22:22:05) [MSC v.1916 64 bit (AMD64)] pySPM 0.2.21 numpy 1.16.4 scipy 1.3.0 matplotlib 3.1.0

Somehow I cannot see your whole code. But the following works for me:

from pySPM_data import get_data
import pySPM.tools.spectra
import pySPM

filename = get_data("Cysteine_B3p_p_01_0.ita")
pySPM.tools.spectra.main(filename)

Can you attach your code as code and not as image? Please use the icon "<>" on the top of the editor.

Now it can be hat the ita file youhave is corrupted. Please run the following:

from pySPM_data import get_data
import hashlib

filename = get_data("Cysteine_B3p_p_01_0.ita")

sha256_hash = hashlib.sha256()
with open(filename, "rb") as f:
    for byte_block in iter(lambda: f.read(4096),b""):
        sha256_hash.update(byte_block)
    print(sha256_hash.hexdigest())

you should get:
