If the analysisprocess has determined that no dots could be discerned in the image, this field shall be setto Y; otherwise, this field will be omitted. See Table 117: Features and Correspondingpresence fields .8.9.7.34 Field 9.345: EFS pores / POREach pore is marked by its center point.When no pores are present, this field shall not be used. See Table 117: Features andCorresponding presence fields .Each pores is represented as a separate repeating subfield consisting of two in<strong>for</strong>mationitems:• The first in<strong>for</strong>mation item (x coordinate / POX) contains the ‘x’coordinate of the center of the pore, in units of 10 micrometers (0.01mm).• The second in<strong>for</strong>mation item (y coordinate / POY) contains the ‘y’coordinate of the center of the pore, in units of 10 micrometers (0.01mm).8.9.7.35 Field 9.346: EFS no dots present / NDOTThis optional field is used to indicate whether the analysis process has determined that nodots are present. If the analysis process has determined that no dots could be discerned inthe image, this field shall be set to Y; otherwise, this field will be omitted.
