Reading data idx culling is not correct related to VoV

[lvarriano]

I try to load data from an LH5 file while passing idx with some range larger than the number of events that the file contains (while making sure that the idx I request is not 0:N since this is handled as a special case so e.g. 1:N). Then I get an error message as attached. errormessage.txt This seems to be a problem for VoV.

import lgdo
import h5py
import numpy as np

store = lgdo.lh5.LH5Store()

input_raw = '/home/lv/Documents/uw/l200/l200-p06-r000-phy-20230619T034203Z-tier_raw.lh5'

ch_list = lgdo.lh5.ls(input_raw)[2:] # skip FCConfig and OrcaHeader

geds_list = []
with h5py.File(input_raw, mode='r') as f:
    for ch in ch_list:
        if 'waveform_presummed' in f[ch]['raw'].keys():
            geds_list.append(ch)

for ch in geds_list:
    chobj, _ = store.read(f'{ch}/raw', input_raw, idx=np.arange(1,5000))
