Hello,
Although there are probably better ways, I would use Import rather than
ReadList
Something like the following ...
list = Import["/Users/..../test.txt", "Table"]
Out[45] = {{"The", "stat", "results", "of", "Quantum", "Dots", "of",
"file",
":", "D:\\ProGram\\qd", "2.1.2\\1.TXT"}, {}, {"totally", 110, "QDs",
"were", "segmented"}, {}, {"QD", "number", "per", "cm^2:",
4.36659*10^10, "per", "cm^2"}, {"mean", "height:", 5.29252,
"nm"}, {"mean", "diameter:", 28.8015, "nm"}, {"mean", "distance:",
33.3098, "nm"}, {"area", "coverage:", 0.291367}, {"volume",
"density:", 0.545079, "nm^3", "per", "nm^2"}, {"mean",
"orientation:", 1.2718, "degree", "with", "x-axis"}, {"mean",
"MajorAxisLength:", 28.3723, "nm"}, {"mean", "MinorAxisLength:",
20.4584, "nm"}, {}, {"Diameter", "Height", "Area",
"MajorAxisLength", "MinorAxisLength", "Orientation", "CentroidX",
"CentroidY", "Volume", "Distance"}, {30.6543, 5.68231, 738.026,
31.1171, 23.1063, -1.62224, 15.3199, 215.548, 1593.05,
48.7416}, {26.0824, 5.76352, 534.3, 25.9359, 20.2485, -27.2306,
10.9906, 349.057, 1109.33, 30.6338}, {16.9929, 2.05731, 226.789,
15.9034, 11.4045, -80.5826, 5.92925, 419.607, 104.23,
32.4718}, {33.1842, 5.23201, 864.874, 33.2583, 23.8731, 2.54486,
33.0374, 170.141, 1416.6, 40.4787}, {34.6983, 6.37284, 945.596,
35.0717, 25.0663, 0.415529, 35.6798, 386.624, 1878.84,
27.9015}, {32.2872, 6.18688, 818.748, 31.8627, 23.3669, -8.17129,
36.0545, 67.1377, 1757.76, 51.3242}}
I can then manipulate the above list. For example,
list[[-7 ;; -1]]
Grid[%]
Or, if I just want data (no headings)
Grid@list[[-6 ;; -1]]
I use Mathematica 6.
