[Radiance-general] Errors while transposing with Rcollate.

[Richard Mistrick]

Something else that is totally bizarre is that if I type your entry on the command line, rcollate crashes with an MSVCR120.dll error, but if I paste Greg's text into the command line it gives me the usage text - and they appear to be completely identical commands.  We are using  the NREL compile of Radiance.

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
