# A list of the first 10 retention times can be returned with:

# In[5]:


print(data.time_list[:10])


# The index of a specific retention time (in seconds) can be returned with:
# 

# In[6]:


data.get_index_at_time(400.0)


# Note that this returns the index of the retention time in the
# data closest to the given retention time of 400.0 seconds.

# The |GCMS_data.tic| attribute
# returns a total ion chromatogram (TIC) of the data
