用法----------Usage----------
data( vfsettings )
格式----------Format----------
This structure contains a variable specifying the number of columns with patient and subject data, locini and several sub-structures with relevant information pertaining different pattern of locations and their analysis. Information exists for the test patterns p24d2, p30d2, p10d2, and sgrnfl. Each sub-structure contains three items:
此结构中包含的变量指定的列数与耐心和主题数据,locini和几个子结构与相关有关的信息不同的图案的位置和它们的分析。信息存在的测试模式p24d2,p30d2,p10d2和sgrnfl。每个子结构包含三个项目:
bs locations that correspond to the ananomical region where the blind spot is. For 24-2, those are locations 26 and 35. There are non for the 10-2
bs对应于的ananomical盲点区域的位置。 24-2,那些位置26和35。有非为10-2
locnum total number of locations of the testing pattern in which stimuli are presented. For 24-2 there are 54 locations, for 30-2 there are 76, for 10-2 there are 68
locnum刺激呈现的测试模式,在该模式中的位置的总数。为24-2有54个,有76个为30-2,10-2有68个
locrPD specifies the rank TD value to be used for the derivation of TD. For 24-2, that ranked location would be 7, corresponding approximately (but not very) to the 85th percentile. For 30-2 the ranked locatoion taken is 10, but this needs fixing???. The way PD is calculated really for 30-2 is by taking the 24-2 locations and finding the seventh largest
locrPD指定要用于推导TD的秩TD值。 24-2,是排名第一的位置将是7,相当于(但不很)第85百分位。对于30-2的排名locatoion的措施是10,但是这需要固定?? PD计算真正为30-2,以24-2的位置和第七大
