Modify cylc graph but only in first year

nice :smiley:

Thanks a lot for the info, very helpful.

I’ve subsequently realised that (I think) the solution should be even simpler than this.

This is the bit of the site file which I have inherited…

[scheduling]
   [[dependencies]]
      [[[ 0101T/P1Y ]]]
         graph = """
postproc{{ '_atmos' if SPLIT_PP else '' }}[-{{FMT}}] => retrieve_ozone => redistribute_ozone => coupled & rose_arch_ozone
 """

So this modifies the graph in the suite.rc only on cycle points that start on January 1st. In this suite the resubmission period is 3 months.

Referring back to the other ticket and specifically Oliver Saunders’ reply I think all I need to do is this…

[scheduling]
   [[dependencies]]
      [[[ 0101T/P1Y!^ ]]]
         graph = """
postproc{{ '_atmos' if SPLIT_PP else '' }}[-{{FMT}}] => retrieve_ozone => redistribute_ozone => coupled & rose_arch_ozone
 """

… where ! is ‘not equal to’ and ^ is the first cycle point.

Let me know if you disagree!

Cheers
