a problem of SD and SSD
why do I calculate the SD and SSD of big neuron like fruit
fly and mouse are very large ，follow is my program based on the
paper of Han Peng
clear all;
op_swc=importdata('E:\neuron-photo\p_checked6_fruitfly_larvae_gmu\done_1_CL-I_X_OREGON_R_ddaD_membrane-GFP\v3dpbd_MOST.swc');
stand_swc=importdata('E:\neuron-photo\p_checked6_fruitfly_larvae_gmu\done_1_CL-I_X_OREGON_R_ddaD_membrane-GFP\1_CL-I_X_OREGON_R_ddaD_membrane-GFP.tif.v3dpbd.swc');
sum_distance=0;
SSD=0;
for i=1:length(op_swc)
min_distance=200;
for j=1:length(stand_swc)
distance=sqrt(((op_swc(i,3)-stand_swc(j,2))^2+(op_swc(i,4)-(stand_swc(j,3)))^2+(op_swc(i,5)-stand_swc(j,4))^2));
if distance min_distance=distance;
end
end
if min_distance>2
SSD=SSD+1;
end
sum_distance=min_distance+sum_distance;
end
SD=sum_distance/length(op_swc);
clear all;
op_swc=importdata('E:\neuron-photo\p_checked6_fruitfly_larvae_gmu\done_1_CL-I_X_OREGON_R_ddaD_membrane-GFP\v3dpbd_MOST.swc');
stand_swc=importdata('E:\neuron-photo\p_checked6_fruitfly_larvae_gmu\done_1_CL-I_X_OREGON_R_ddaD_membrane-GFP\1_CL-I_X_OREGON_R_ddaD_membrane-GFP.tif.v3dpbd.swc');
sum_distance=0;
SSD=0;
for i=1:length(op_swc)
min_distance=200;
for j=1:length(stand_swc)
distance=sqrt(((op_swc(i,3)-stand_swc(j,2))^2+(op_swc(i,4)-(stand_swc(j,3)))^2+(op_swc(i,5)-stand_swc(j,4))^2));
if distance min_distance=distance;
end
end
if min_distance>2
SSD=SSD+1;
end
sum_distance=min_distance+sum_distance;
end
SD=sum_distance/length(op_swc);

RE: a problem of SD and SSD
The source code to calculate these two distance scores is here https://github.com/Vaa3D/v3d_external/bl.... Please check it.
