Can I see Tombo Index File

[yuxinPenny]

I want to extract the current signal when a base pass through the nanopore. i.e. the current signal value for each position on the read. It seems that this information is stored on the Tombo Index File, It there any way that I can access the tombo index file produced after re-squiggle.

There is no command line tools for this, but the API is your best tool for this question. You can see the beginning steps here in the docs. The get_base_levels function will get the signal summary at each position (https://nanoporetech.github.io/tombo/tombo.html#tombo.tombo_helper.intervalData.get_base_levels). The get_single_slot_read_centric function can be used to extract the raw signal start positions see docs here.
