I have been able to initiate Omicron after much trial and error, however now I am stuck with an error.

Using a list of gps times for H1 for O3a run from [https://gwosc.org/O3/auxiliary/](https://gwosc.org/O3/auxiliary/), also attached to this email, I have tried to run the omicron over one aux channel named H1:DCS-CALIB\_STRAIN\_CLEAN\_C01.

While the Omicron initiates, it ends with the following error upon reading the time segment (GPS) file. I have tried both the csv and txt versions of time segment file but both end up with the similar error “Segments::Segments: number of col = 0 is not supported” for a csv and Segments::Segments: number of col = 0 is not supported" for a text file.

Could someone please help me identify the error?

This was my CLI command “omicron times.txt CONFIG.ini” and the output is attached here:

The problem is the format of your segment list. Do not use a comma as a separator. Simply separate the 2 columns by a white space.
