ARRFile output in two lines instead of one

[IvanaEscobar]

Current behavior:

Previously, ARRFile printed output on a single line in the format:

Amplitude       phase          delay         delay(imag)     start angle     end angle      bounce top   bounce bottom
7.2071263E-05   1862.231       9.524935      0.0000000E+00   22.00000        -54.49823      7            8

uwapm.py provides a way to read data on a single line as data: https://github.com/org-arl/arlpy/blob/003b3111ab9aa17666af7af71e3b015734f028c1/arlpy/uwapm.py#L782-L798

Issue:

ARRFile prints output over multiple lines, with end angle, top, and bottom bounces on a second line:

Amplitude       phase          delay         delay(imag)     start angle     
7.2071263E-05   1862.231       9.524935      0.0000000E+00   22.00000        
end angle      bounce top   bounce bottom
-54.49823      7            8

Sample arrival output compiled in a Linux-GNU x86_64 machine with ifort (IFORT) 180.0 20170811.

Personal resolution:

In uwapm.py, read in two lines at a time for arrivals data: https://github.com/IvanaEscobar/arlpy/blob/5ba7be0e4ef0f27ea9dca74d2c6ac5ccfb991329/arlpy/uwapm.py#L779-L796

@IvanaEscobar, the personal resolution you have will fail with older versions of Bellhop, I presume?

[IvanaEscobar]

I don’t have access to older versions of Bellhop, but if you do please send me the files and I’ll check.

That's the version I am running now. So I'll check in a blank shell environment to see if it's an artifact of my environment or a BELLHOP feature.

I tested with v2022_4_20 and got the format we expect (single line):

@mchitre I figured out the underlying issue caused by compilers. Credit to this thread.

I adjusted my compiling flags by adding -no-wrap-margin, and was able to avoid a two lined output. Do you know of a way to officially contribute to the Acoustics Toolbox? This update would be useful for other Intel compiler users.

[IvanaEscobar]

P.S. Also checked with the newest version of Bellhop and the ARRFile has not changed its format

[mchitre]

Ah, makes sense, compiler quirks! :-)

You may want to get in touch with Michael Porter, who is the author of OALIB to contribute.
