[Radiance-general] Errors while transposing with Rcollate.

[Sarith Subramaniam]

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
