[Radiance-general] Errors while transposing with Rcollate.

[Greg Ward]

Well, that was quicker than expected.  Just after sending this e-mail, Sarith wrote again and the problem seems to be resolved.  He had an old version of rcollate that didn't work when stdin was redirected from a file, but the latest works in that mode with -t but not from a file under Windows.  This was easy enough to fix, and the next NREL release should behave properly.  Meanwhile, Windows folks may have to redirect the input when transposing ASCII files with rcollate.

A tempest in a teacup, really....

Cheers,
-Greg

>> 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.

>> 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.

>> 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.
