Error in bandpass_filter

[mstux]

Hi! I get this error when trying to sort my data:

Any ideas why? Thank you

I think you are running out of RAM. How much RAM to you have on your system?

[mstux]

7,7 GiB

[magland]

What is the size of your raw data? Please try mda /home/fisio/Scrivania/Progetto_prova/bigfiles/prova1/pr2_raw.mda

(how many channels?)

[mstux]

{ "data_type": -7, "data_type_string": "float64", "dims": [ 20000000, 1 ], "header_size": 20, "num_bytes_per_entry": 8, "num_dims": 2 }

Only one channel. I also tried with a smaller file, the error changes but it is still an error:

You need to transpose the array. It thinks there are 20000000 channels because that is the first dimension. The first dimension is the channel dimension.

Thank you!
