The +playlist is just an index of the force curve files you want to +analyze. Imagine it as a music playlist (that’s why it is called a +playlist), but made of data files instead of MP3s (or FLACs :p). + +Suppose you have 100 PicoForce curve files in your curves directory, +starting from mycurve.000 and ending in mycurve.100 and you want to +analyze them all. + +You then can cd to the directory + + hooke: cd c:\curves + +Type pwd to check the directory is correct + + hooke: pwd + c:\curves + hooke: + +You can list the files in the directory using ls or dir (they’re synonims) + + hooke: ls + [’mycurve.000’, ’mycurve.001’, ...] + +Now you are ready to generate the playlist. The command to use is genlist + + hooke: genlist mycurve.* + +You can also generate a playlist containing all what you find in the +directory by typing: + + hooke: genlist c:\curves + +If you want to select what curves to see, based on the filename, you +can use wildcards. + + For example: + + hooke: genlist mycurve.05* + +will take only curves from mycurve.050 to mycurve.059. + +Saving and loading playlists +---------------------------- + +Note that by using genlist you just generate the playlist in the local +session. To save your playlist to a file, thus avoiding to regenerate +it, type: + + hooke: savelist mylist + +The list will be saved, in this example, in the file mylist.hkp. Hooke +will add the extension .hkp to the playlist if you forget to. The .hkp +file is an XML file you can read and edit with any text editor +(i.e. Wordpad), if needed. If you want to load it, just issue loadlist +mylist.hkp or loadlist mylist, Hooke will handle the missing .hkp +extension. This will load the saved playlist, as if you just generated +it. + +Generating the playlist, you should see the plot of the first curve +appearing. If, generating the playlist, you are including by chance a +non-force curve file that Hooke cannot open, it should be (more or +less) silently ignored. If it gives some error, or it does not plot +anything, try to navigate forward, and see if the next curve is +plotted; it is possible you spotted a corrupted file. Navigate the +playlist + +Navigating playlists +-------------------- + +Now you can navigate through your playlist using the command next and +previous or, more easily, their aliases n and p. You don’t need to +type n every time to run along a list of curves. If you press Return +to an empty prompt, Hooke will repeat the last command you issued +explicitly. + +You can also navigate through the command history by using the up and +down arrows. + +When arriving to the last curve of your playlist, pressing n will just +come back to the first. Analogously, pressing p when at the first +curve will jump to the last. + +You can also jump to a given curve, this way: + + hooke: jump c:\curves\mycurve.123 + +but be careful to tell Hooke the full path to that curve, otherwise it +will not find it. + + +Taking notes +============ + +You can take notes about the curves you are looking at. Just type note +followed by the text you want to append to that curve. Hooke will save +the text in your current playlis and in an external log file. The +output will look like this: + + Notes taken at Sun Sep 17 20:42:07 2006 + /home/cyclopia/work/tris/20060620a.041 | This is a note + /home/cyclopia/work/tris/20060620a.207 | This is another note + /home/cyclopia/work/tris/20060620a.286 | This is a third one + +The first time you type note in a session, Hooke will ask you for a +filename of the log. + +Usually curves you annotated are useful later. You can copy the curves +you annotated in a different directory by using the copylog command, + + hooke: copylog c:\nicecurves + +which will copy all curves you have annotated in the c:\nicecurves +directory. Take care that the directory already exists before doing +that. + + +Exporting curves +================ + +You can export Hooke curves as images and as text columns. To export +as images, issue the export command followed by the +filename. Supported formats are PNG (raster) and EPS (Encapsulated +Postscript, vector). The export format is determined by the filename +extension, so export foo.png and export foo.eps will save a PNG and +EPS file respectively. + +To export as text, use the txt command, followed by the filename. The +output is a text file containing columns (first two are X and Y of +extension, last two are X and Y of retraction). + + +Interacting with the plot +========================= + +Measuring distances and forces +------------------------------ + +You can easily zoom in the plot by dragging a rectangle on it with the +left mouse button. To zoom out, click the right mouse +button. Sometimes by zooming in and out too much, you can lose the +picture (this is probably a small bug in Matplotlib). Just type plot +at the command line and the curve will be refreshed. + +You can measure distances and forces directly in the plot. Just issue +the command distance. You will be asked to click two points: do +it. When you click a point, a blue dot should appear. When you click +the second point, the distance (in nanometers) will apper on the +command line. force works in the same way. You can use delta if you +prefer, which gives meaningful values for every kind of graph (not +only force curves). If you want to know the coordinates of a single +point, use point. + +Hooke automatically adjusts the position of the clicked point at the +nearest point in the graph, so you will be always measuring distances +and forces between points in the graph. + +The commands force and distance are present in the generalvclamp.py +plugin. + +Worm like chain fitting +----------------------- + +You can measure by hand the parameters relative to a force peak using +a worm-like chain fitting with the wlc command. The command by default +automatically finds the contact point, asks for two points delimiting +the portion to fit, and performs a two-variable fit, with contour +length and persistence length as output, with relative errors. If +desired, one can use the noauto option to manually click the contact +point, and/or the pl=[number] options to impose a specific persistence +length (in nanometers). Please see the help of the wlc command from +the Hooke command line for details. + +Variables +--------- + +You can set environment variables to influence the behaviour of +Hooke. The command to use is set. + +You can alter permanently the behaviour of Hooke by setting these +variables in the file conf/hooke.conf. This is a very simple XML file, +just change the values of the variables with an ASCII text editor (not +Word or a word processor - on Windows, Wordpad should work). Be +careful with the correct XML syntax (which you should grasp very +easily looking at the default configuration file) otherwise Hooke will +crash on the next startup. + +See VariableList for help on individual variables.
