[Radiance-general] Pipe Transmission Matrix in 3 Phase Method

[Islam Mashaly]

Hello,
I am trying the 3 phase method example of the pipe that Andy made in the presentation. I am doing it using the sensor points method. It went smooth in the (Daylight Matrix, View Matrix, both BSDF.xml files) however there is a problem in the "pipe transmission matrix".
I am not sure when he meant in this line:
rfluxmtx -n 8 -ab 12 -ad 1000 -lw 1e-4 objects/LP_bottom.rad objects/LP_top.rad materials_glow.rad objects/LP_sides.rad  > results/LP_trans.mtx
whether i should give the pipe a glow material or should i give it to the "top part" the glow material?
Another thing, do I have to insert the whole model.rad or the Light pipe sides should work fine?
I tried several options:
giving the sides a glow material, however when it ran it gave me several errors and a warning
rfluxmtx: internal - sample behind all sender elements!rcontrib: warning - partial accumulation in final recordrcontrib: fatal - unexpected EOF on input
I wish I could know why each error appears.
But in the end it generates a matrix file but the numbers inside seems irrational as they are all nx10^-5

However when I put glow materials to the top of the pipe only it gives me the following warning:
rcontrib: warning - aiming failure for light source "ttttttttt.nnn" t= text n=numbers
and it seems to be frozen and does not generate any matrix.
Is there any advice on what should be done to generate a pipe matrix and what materials to use?
Thanks for you assistance,Islam Mashaly.
