Hi Yasmin,
My apologies for the late reply. What is the error you encounter when trying to use read.pcibex? That function should output a table whose columns are named after the comments lines
1.655924e+12 is a visual representation of a number composed of 13 digits used by whatever software you are using to view it, but the internal representation of the number is effectively between 1655924000000 and 1655924999999 (depending on how the software decided to truncate/round the number in its exponent representation)
