Hi @Elladt , thanks.

[lietava]

@shahor02 : why the checks are pending ?

[shahor02]

Approving conditionally to trigger CI.

@lietava @Elladt could you please comment on where and how this workflow should be used? Its DPL output is the same as of the CTP/workflow/src/RawDecoderSpec.cxx, and the code seems to be largely cloned from the latter.

Uploading Ella_Summer_Student_Report.pdf…
Hi @shahor02 , it is work in progress done by summer student @Elladt .
The goal is to replace non o2 ctp sw which creates massi files and maybe more things.
It is to be discussed with lhcif and to be employed before run4.

[shahor02]

@lietava the CI errors are genuine (missing includes?)

[lietava]

HI @shahor02 , yes include filesystem seems to solve problem.
Can I push to this PR ?

[shahor02]

@lietava no, but I've added the include by direct edit.

[lietava]

@shahor02 , thanks.

re-approving conditionally to restart CI
