Potential bug in def apply(self, dims=['drift_time', 'retention_time'], resolution=[0.01, 0.01])

[rpisalive]

Hello,

I tried to perform MS2 deconvolution according to the steps demonstrated:
https://deimos.readthedocs.io/en/latest/user_guide/ms2_extraction.html

I used the provided example_data.h5 and example_data_peaks.h5 files provided at:
https://massive.ucsd.edu/ProteoSAFe/dataset.jsp?task=749e436db868410383159b450b470eff

When I run res = decon.apply(dims='drift_time', resolution=0.01), it returned the following error:

---

TypeError Traceback (most recent call last)
in

~/.conda/envs/deimos/lib/python3.7/site-packages/deimos/deconvolution.py in apply(self, dims, resolution)
370 for name, grp in self.decon_pairs.groupby(by=["index_ms1"], as_index=False):
371 # MS1 feature index
--> 372 idx_i = int(name[0])
373
374 # Extracted ion

TypeError: 'int' object is not subscriptable

Removing the [0] solved the error and I received the expected output.
