 -f config     (--input)       read an input file in .inp or .json format

== MC options ==
 -n [0.|float] (--photon)      total photon number, max allowed value is 2^32-1
 -b [0|1]      (--reflect)     1 do reflection at int&ext boundaries, 0 no ref.
 -U [1|0]      (--normalize)   1 to normalize the fluence to unitary,0 save raw
 -m [0|1]      (--mc)          0 use MCX-styled MC method, 1 use MCML style MC
 -C [1|0]      (--basisorder)  1 piece-wise-linear basis for fluence,0 constant
 -u [1.|float] (--unitinmm)    define the mesh data length unit in mm
 -E [1648335518|int|mch](--seed) set random-number-generator seed;
                               if an mch file is followed, MMC "replays" 
                               the detected photons; the replay mode can be used
                               to calculate the mua/mus Jacobian matrices
 -P [0|int]    (--replaydet)   replay only the detected photons from a given 
                               detector (det ID starts from 1), use with -E 
 -M [H|PHBSG] (--method)      choose ray-tracing algorithm (only use 1 letter)
                               P - Plucker-coordinate ray-tracing algorithm
			       H - Havel's SSE4 ray-tracing algorithm
			       B - partial Badouel's method (used by TIM-OS)
			       S - branch-less Badouel's method with SSE
			       G - dual-grid MMC (DMMC) with voxel data output
 -e [1e-6|float](--minenergy)  minimum energy level to trigger Russian roulette
 -V [0|1]      (--specular)    1 source located in the background,0 inside mesh
 -k [1|0]      (--voidtime)    when src is outside, 1 enables timer inside void
 --atomic [1|0]                1 use atomic operations, 0 use non-atomic ones

== Output options ==
 -O [X|XFEJLP] (--outputtype)  X - output flux, F - fluence, E - energy deposit
                               J - Jacobian, L - weighted path length, P -
                               weighted scattering count (J,L,P: replay mode)
 -s sessionid  (--session)     a string used to tag all output file names
 -S [1|0]      (--save2pt)     1 to save the fluence field, 0 do not save
 -d [0|1]      (--savedet)     1 to save photon info at detectors,0 not to save
 -x [0|1]      (--saveexit)    1 to save photon exit positions and directions
                               setting -x to 1 also implies setting '-d' to 1
 -q [0|1]      (--saveseed)    1 save RNG seeds of detected photons for replay
