Error during OspreyProcess: unrecognized file name "np_sw_2080_2399.808"

Dear @admin / @Helge ,

I have come across an error in OspreyProcess (using the latest version, cloned today) that wasn’t present in an older version of Osprey I cloned on the 11th of March 2022. I can still run OspreyProcess in the older version but it would be nice to keep up to date with any future developments.

The error is below:

Please let me know if you would like any additional information.

Many thanks,

Hi @CarolynMcNabb,

Thanks for reaching out and keeping up with the most recent developments.

I’ve just pushed a bug fix for your issues to the develop-branch. It was related to the spectral bandwidth being a non-integer number which broke Matlab struct that stores the data. I have tested the fix with some of the data you send me to fix an older issue that also had non-integer spectral bandwidth.

Let me know if this works for you.

Best,
Helge
