54 :     <h1>Help On SEED/PIR Comparisons</h1>
55 :     <center>Rob Edwards April 1, 2005</center>
56 :    
57 :     <p>The SEED/PIR comparisons are controlled by the script <a href="/FIG/pir.cgi">pir.cgi</a>. These are the functions in this script.</p>
58 :    
59 :     <p>There are lots of ways of comparing the data between the SEED and the PIR superfamilies. You can enter the comparison directly using the list menu, can can ask for those proteins that are in many superfamilies or in many subsystems, and you can enter directly via the spreadsheets. This help should guide you on some of the entry points and what the data means. It is accessible from the links on the appropriate pages to remind you when necessary.</p>
60 :    
61 :    
62 :    
63 :     <p>First we have a simple comparison of PIR and SEED functions. The list provides a summary of the PIR superfamilies, and the number of PEGS that map to that superfamily directly. There should be a many-to-one relationship here because each superfamily has many pegs in it.<br />
64 :    
65 :     Immediately below the list there are some options to control which superfamilies are displayed in the list:</p>
66 :    
67 :     <a name="menu"><h2>Control menu contents</h2></a>
68 :     <p>You can control the number of pegs that the superfamily must contain. Using this option you can limit the list to those superfamilies that have multiple PEGs in the SEED database, and are therefore likely to be more consistent.
69 :     <span class="example">Minimum number of pegs per PIR superfamily shown in list &nbsp; <input type='text' name='min' value='10' size=3 /></div>
70 :     </p>
71 :     <p>You can also choose to show all superfamilies (note, this is the same as setting the minimum number to 1): <span class="example">or show all PIR superfamilies: <input type="checkbox" name="showall" value="on" /></span></p>
72 :     <p>The next option is to show the subsystem counts in the menu. This shows the correspondence between PIR superfamilies and SEED subsystems. This doesn't have to be a one-to-one relationship because one superfamily can be represented by more than one subsystem. <br />For example, "Pyrophosphate--fructose 6-phosphate 1-phosphotransferase, alpha subunit (EC 2.7.1.90)" is in subsystems for "Embden-Meyerhof and Gluconeogenesis" and "Fructose_and_Mannose_metabolism".
73 :     Checking the box will show the correspondence. On some machines this may take a minute or two to compute.<br />
74 :     <span class="example"><input type="checkbox" name="showsubsys" value="on" />Show subsystem counts in list</span>
75 :     </p>
76 :    
77 :     <p>By default the list only shows the Fully annotated PIR superfamilies, and not the preliminary superfamilies. However, you can reverse this, and display only the preliminray superfamilies if desired. The correspondences in preliminary superfamilies may be less well developed. <span class="example"><input type="checkbox" name="preliminary" value="on" />Show only preliminary PIR superfamilies</span>
78 :     </p>
79 :    
80 :     <p>The three choices are to update the view which will present the same page, but with the choices that you have selected here, to show the correspondence between PIR superfamily and the SEED, and to reset the list back to the original values. The correspondence is <a href="#correspondence">described below</a></p>
81 :    
82 :     <a name="datatables"><h2>Generate Data Tables</h2></a>
83 :    
84 :     <p>Generating the tables takes about five minutes, and so you need to be patient and wait for the results. Resist the temptation to keep clicking the button.</P>
85 :     <p>The two options are to select what types of data are presented. See below for an example of the data that will be returned.</p>
86 :    
87 :     <p>The first choice allows you to decide on the correspondence that you want to see. If you click the box (the default) you will only see those superfamilies that have proteins that are in subsystems. A superfamily has several proteins in it, and some of those may be in subsystems as well as superfamilies. However there are also superfamilies whose proteins are not in subsystems. These are not shown by default because we do not make any assertions about the annotations of those proteins.</p>
88 :    
89 :     <p>The second choice allows you to sort the table that is returned. The data can either be sorted by the "Number of annotations in subsystems" or by the "Number of SEED annotations". See below for a description of these.</P>
90 :    
91 :     <p>The table that is returned will look something like this:

151 :     <li>Number of annotations in subsystems</li>
152 :     <p>This is the nummber of different annotations that this superfamily has, only considering those annotations that are in subsystems. A large number indicates that the superfamily covers proteins with different roles in the subsystems, and there is probably a conflict between the superfamily and the SEED. These are the superfamilies or subsystems or annotations that need most attention.</p>
153 :     <li>Number of SEED annotations</li>
154 :     <p>This is the total number of different annotations that this protein family encompasses in the SEED, including those proteins that are not in subsystems. A lower number is also better, and the excess over the first column probably represents the proteins that have yet to be included in superfamilies yet.</p>
155 :     <li>PIRSF</li>
156 :     <p>The number is the number of the PIR superfamily, and the link takes you to the correspondence between this superfamily and the SEED database. See the <a href="#correspondence">correspondence</a> help below.</p>

253 :     <a name="updates"><h2>Update Data</h2></a>
254 :     <p>You can download new data from the PIR ftp site and install the data directly. This is a two step process. First, we check to see whether the new file is more current than the old one (there is no point updating otherwise, unless, of course, you have added new genomes). Second, we actually get the data.</p>
255 :    
256 :     <p>Click on the <span class="example"><input type="submit" name="submit" value="Check for updates" /></span> button to see whether there are new updates. You will then see a page that looks something along these lines (of course, the times will be different!):</p>
257 :    
258 :     <p>This example is for files that are all current.</p>
259 :     <div class="example">
260 :     <p>The local file is up to date and there is no need to update your source PIR superfamilies.</p><p>The remote file was modified on Fri Jan 14 13:26:47 2005</p><p>The local file was modified on Sat Jan 29 11:31:55 2005</p>
261 :     <input type="submit" name="submit" value="Update Anyway" />
262 :     </div>
263 :    
264 :     <p>If your files are not current, then the message will be something like this:</p>
265 :     <div class="example">
266 :     <p>The remote file ftp://ftp.pir.georgetown.edu/pir_databases/pirsf/data/pirsfinfo.dat is newer than your current file. You should proceed with the update.</p>
267 :     <p>The remote file was modified on Fri Jan 14 13:26:47 2005</p>
268 :     <p>The local file was modified on Wed Dec 29 11:31:55 2004</p>
269 :     <input type="submit" name="submit" value="Update Data" />
270 :     </div>
271 :    
272 :     <p>If there is a problem with the internet connection or the file can not be accessed for some reason (e.g. the name is wrong), you will not be given the option to proceed with the update like this:</p>
273 :     <div class="example">
274 :    
275 :     <p class="error">Could not connect to PIR to check the status of the PIR file. Please check the location of ftp://ftp.pir.georgetown.edu/pir_databases/pirsf/data/pirsfinfo.dat</p>
276 :    
277 :     </div>
278 :    
279 :     <p>Clicking on the "Update Data" or "Update Anyway" buttons will start the download and reinitiate the comparison of the SEED data with the PIR data. This starts a complete install of the PIR data which may take some time, so you will have to be patient! You can also use this to refresh or reinstall your data if you believe that the data is out of date (for example if you have added new genomes).</P>
280 :    
281 :     <p>Once the update is run, you will see the front page again, however there will be a message telling you that the update is complete</p>
