[Radiance-general] Errors while transposing with Rcollate.

[Guglielmetti, Robert]

Looks like a line endings problem. If I create an input text file on Windows and run rcollate, I get the "error loading file into memory" error. But if I create an input text file on the Mac, copy it to my Windows VM and run rcollate, it works fine with the first invocation David lists below. What I don't know about this crap could fill a book, but I am ASSuming rcollate lacks certain file type handling that other radiance programs have. (?) HTH, YMMV, EIEIO, TTFN

Hi Sarith,

I just tried both calls (with and w/o redirecting from stdin) with the latest Windows binaries from NREL(https://github.com/NREL/Radiance/releases) and both work fine at my side...

rcollate -h -fa1 -t a.txt > d.txt
rcollate -h -fa1 -t < a.txt > d.txt

Which version of rcollate are you using?

Best,
David

Anyone else have any ideas or suggestions?  Honestly, I don't know why redirecting stdin from a file would fail completely.  I thought this was supported under Windows.

I'm stumped.

Hi Greg,


The command that you suggested returns the usage options for rcollate in windows. (ie.  Usage: rcollate [-h[io]...........)

Earlier, I had tried feeding the file to rcollate via stdin through using pipe ( | ) as well as the 'type a.txt' shell command in windows but didn't get it work either way.


Thanks,
Sarith

Hi Sarith,

This seems related to the broken handling of text versus binary files under Windows.  Try reading the file from stdin, instead:

rcollate -h -fa1 -t < a.txt > d.txt

If this works, let me know and I'll see if I can put in a fix.

Cheers,
-Greg

Hi everyone,


I am trying to do a transpose with rcollate. My operating system is Windows. My file contains rgb triplets arranged in a (8760columns x 60rows) matrix. I either get a "error loading file into memory" or an incorrect transpose.


I found that I got the same results with a simple ASCII file with tab separated values. My file contains:

1          2          3          4
5          6          7          8
9          10         11         12


The following commands return "error loading file into memory":

rcollate -h -fa1 -t a.txt >d.txt

rcollate -h -fa1 -ic 4 -oc 3-t a.txt >d.txt


I found that the '-t' flag was responsible for the error, so I tried explicitly stating the values for columns and rows as:

rcollate -h -fa1 -ic 4 -ir 3 -oc 3 -ir 4 a.txt>d.txt

This gave me.
1          2          3
4          5          6
7          8          9
10         11         12


Am I missing something?


Thanks,
Sarith
