I was searching how to add -C (Use the center of the block as the output location) in pygmt.blockmean command line.
Thank you.

I was searching how to add -C (Use the center of the block as the output location) in pygmt.blockmean command line. Thank you.

Thanks @crystalratna for trying out PyGMT and apologizes for the late response!

Currently, there is no alias available for -C for the pygmt.blockmean function in PyGMT. Maybe you can try C=True (related to https://docs.generic-mapping-tools.org/dev/blockmean.html#c), but I am not sure about this.
Ping @GenericMappingTools/pygmt-maintainers for help on this, please.

If this comment is meant as a request for adding an alias for -C for the pygmt.blockmean function, please open a separate issue. Probably this comment was overlooked as it is written in a merged PR.

Please see the extended line example below:

# sourec: https://www.pygmt.org/dev/api/generated/pygmt.blockmean.html#pygmt.blockmean
# last acces: 2022/11/06
import pygmt
# Load a table of ship observations of bathymetry off Baja California
data = pygmt.datasets.load_sample_data(name="bathymetry")
# Calculate block mean values within 5 by 5 minute bins
data_bmean = pygmt.blockmean(
    data=data,
	region=[245, 255, 20, 30],
	spacing="5m",
	C=True,  # Use the center of the block as the output location
)
