Hello @Greg_Ward,
Thank you for your reply. I have uploaded the file to my google drive:

I don’t think the problem is coming from 4.pts since the following command runs fine:
c:\radiance\bin\rcontrib -aa 0.0 -ab 0 -ad 512 -ar 16 -as 128 -dc 1.0 -dj 0.0 -dp 64 -ds 0.5 -dr 0 -dt 0.0 -I -lr 4 -lw 0.05 -M .\sky\analemma.mod -ss 0.0 -st 0.85 analemma.oct < 4.pts > result\matrix\sun_4..scene..default.dc
but the one with using rfluxmtx will give me the EOF error.
I also tried the same stuff on my other laptop, and it works absolutely fine. So this is an isolated case. Do you happen to know what might cause this?
