收藏资源简介:
<p>Below are the descriptions of the Matlab \".mat\" data files in the attached file \"MarineSnowLayers_CopepodTracksData.zip\".</p> <p>All Matlab files are named in the following format:</p> <p><em>EXPX_TR_CAMYY_Track_ZZ</em></p> <p>where \"X\" will be 1, 2, 3, or 4 corresponding to the Experiment number of the track,<br /> \"TR\" will be CG (representing control with gradient treatment), CNG (representing control with no gradient treatment), Homogenous (representing homogenous treatment), or Layer (representing layer treatment),<br /> \"YY\" will be either 01 or 02 representing the camera number, and<br /> \"ZZ\" will be a number representing the copepod track number.</p> <p>The total number of tracks varies by treatment and experiment according to the table below:</p> <p><strong>Exp. Treatment Camera Number of Tracks</strong></p> <p>1 CG 01 36</p> <p>1 CNG 01 28</p> <p>1 Homogenous 01 25</p> <p>1 Layer 01 52</p> <p>1 CG 02 20</p> <p>1 CNG 02 26</p> <p>1 Homogenous 02 34</p> <p>1 Layer 02 40</p> <p>2 CG 01 37 </p> <p>2 CNG 01 23</p> <p>2 Homogenous 01 42</p> <p>2 Layer 01 69</p> <p>2 CG 02 26</p> <p>2 CNG 02 25</p> <p>2 Homogenous 02 28</p> <p>2 Layer 02 50</p> <p>3 CG 01 26</p> <p>3 CNG 01 23</p> <p>3 Homogenous 01 23</p> <p>3 Layer 01 62</p> <p>3 CG 02 15</p> <p>3 CNG 02 21</p> <p>3 Homogenous 02 25</p> <p>3 Layer 02 30</p> <p>4 CG 01 27</p> <p>4 CNG 01 30</p> <p>4 Homogenous 01 19</p> <p>4 Layer 01 59</p> <p>4 CG 02 28</p> <p>4 CNG 02 20</p> <p>4 Homogenous 02 32</p> <p>4 Layer 02 52</p> <p> </p> <p>Each Matlab file contains the same three vectors depending on the camera:<br /> <em>cop_xloc_cm</em> (for Camera 1) or <em>cop_yloc_cm</em> (for Camera 2)<br /> <em>cop_zloc_cam1_cm</em> (for Camera 1) or <em>cop_zloc_cam2_cm </em>(for Camera 2)<br /> <em>time_cam1</em> (for Camera 1) or <em>time_cam2</em> (for Camera 2)</p> <p>The <em>cop_xloc_cm</em>/<em>cop_yloc_cm </em>provide the horizontal location of the copepod in cm from the edge of the tank (defined as the x direction for Camera 1 and the y direction for Camera 2).</p> <p>The <em>cop_zloc_camX_cm </em>vectors provide the vertical location of the copepod in cm from the bottom of the tank in Cameras 1 and 2, respectively.</p> <p>And the <em>time_camX</em> vectors provide the time in seconds since the first copepod appeared in the field of view.</p> <p>All three of the vectors in each individual Matlab file are the same length and indicate the number of sequential images that the copepod was tracked.</p>
下述为附件压缩包"MarineSnowLayers_CopepodTracksData.zip"中所含Matlab格式(.mat)数据文件的详细说明。 所有Matlab数据文件均遵循统一命名格式: <em>EXPX_TR_CAMYY_Track_ZZ</em> 其中,X取值为1、2、3或4,对应该追踪序列所属的实验编号;TR为实验处理组标识,可选值包括CG(代表带梯度处理对照组)、CNG(代表无梯度处理对照组)、Homogenous(代表均质处理组)以及Layer(代表层状处理组);YY取值为01或02,对应摄像机组编号;ZZ为正整数,代表该桡足类的追踪序列编号。 各实验、各处理组下的追踪序列总数如下表所示: <strong>实验编号 处理组 摄像机组编号 追踪序列数量</strong> 1 CG 01 36 1 CNG 01 28 1 Homogenous 01 25 1 Layer 01 52 1 CG 02 20 1 CNG 02 26 1 Homogenous 02 34 1 Layer 02 40 2 CG 01 37 2 CNG 01 23 2 Homogenous 01 42 2 Layer 01 69 2 CG 02 26 2 CNG 02 25 2 Homogenous 02 28 2 Layer 02 50 3 CG 01 26 3 CNG 01 23 3 Homogenous 01 23 3 Layer 01 62 3 CG 02 15 3 CNG 02 21 3 Homogenous 02 25 3 Layer 02 30 4 CG 01 27 4 CNG 01 30 4 Homogenous 01 19 4 Layer 01 59 4 CG 02 28 4 CNG 02 20 4 Homogenous 02 32 4 Layer 02 52 每个Matlab数据文件均包含三组与对应摄像机组匹配的向量: <em>cop_xloc_cm</em>(摄像机组1)或<em>cop_yloc_cm</em>(摄像机组2) <em>cop_zloc_cam1_cm</em>(摄像机组1)或<em>cop_zloc_cam2_cm</em>(摄像机组2) <em>time_cam1</em>(摄像机组1)或<em>time_cam2</em>(摄像机组2) <em>cop_xloc_cm</em>与<em>cop_yloc_cm</em>用于记录桡足类相对于培养槽边缘的水平位置,单位为厘米:其中摄像机组1的水平方向定义为x轴方向,摄像机组2的水平方向定义为y轴方向。 <em>cop_zloc_camX_cm</em>向量用于记录桡足类相对于培养槽底部的垂直位置,单位为厘米,其中X分别对应1和2,分别代表摄像机组1与2的参数。 <em>time_camX</em>向量用于记录自第一只桡足类进入拍摄视野起的累计时长,单位为秒,其中X对应摄像机组编号。 单个Matlab数据文件内的三组向量长度完全一致,其长度代表该桡足类被追踪的连续拍摄总帧数。
