imwrite(I,map,'lung.png','png');

Error using imwrite>parse_inputs (line 628)
The colormap should have three columns.
Error in imwrite (line 440)

I imagine you looked at what map was. Did that not give you any clue as to why it was not 3 columns? What was it? Maybe it's empty, in which case you'd not pass it in to imwrite.

You can't do that. You have to do it like I showed you - inside an "if" block. You can't convert a gray scale or indexed image to RGB if there is no colormap.
And for the gray scale image I assume you got that working already by doing what it told you and casting your image to uint8 with the im2uint8() or uint8() function
grayImage = im2uint8(grayImage);
imwrite(grayImage, outputFileName);
