Hi guys and gals,
I get a question regarding buffer size when looping the file source:
Currently I intent to have an offline processing with some captured data:
read the data (for example, size 1201) from file sources, then handle the
data with certain filtering and so on.... After that I intend to analysis
the data with linear regression in python block. While the read size of
data in GNURadio could not perfectly fit the size 1201 when looping
("REPEAT"=YES) enabled, which causes the linear regression some time happen
between 2 loops of read(tail of the 1st loop and head of 2nd loop) and it
leads to error results of regression.

I tried to adjust the max/min buffer value but it did not work as I
expected. Warnings like "max output buffer set to 1536 instead of
requested 1201" always popped up ...
Any advice and insights?
BR//Jonny
