利用EXCEL表格搞定生物芯片数据.doc

Cell conventions Cells are referred to by their column letter and row number (ex: A2). A series of cells are referred to by showing the starting and ending cells, separated by a colon (ex: A2:A100). When cells are copied and pasted, the column and row are shifted to adjust to the position of the new cell. For example, if the formula =B5 is copied and pasted one cell to the right, the formula in the new cell will change to =C5. If you wish to maintain the position(s) of cell(s) in a formula, use the prefix $ to create an absolute link to cells that wont change with copying an pasting. For example, if the formula =$B$5 is copied and pasted one cell to the right, the formula in the new cell will still be =$B$5. You may use the prefix $ before the column and/or the row. Refer to cell(s) in another worksheet by prefixing the cells with the sheet name plus !. Ex: =data!B4 refers to cell B4 on a worksheet named data. For this reason its very helpful to name worksheets with short but informative names. Refer to cell(s) in another file by prefixing the cells with the file in square brackets and the sheet name plus !. Ex: =[anotherFile.xls]data!B4 refers to cell B4 of file anotherFile.xls on a worksheet named data. Copying and pasting cells Copying and pasting cells usually has the expected result. If not, check your use of $ (to fix a location). When copying and pasting data generated by a formula, it may be best (to prevent re-calculations of data) to paste the actual value, rather than the underlying formula. To do this, copy the cell(s) as usual but then select Paste Special Values. Using functions Excel contains a reasonable range of functions which can be used by in one of at least two ways: Type the formula (preceded by =) in the box next to fx near the top of the window, along with all of the required arguments (assuming you know what these are). Select Insert Function and then choose the function you wish. Select a category to get a partial or complete l
