Q.
W h y does C A T C H pop up a file chooser when I load the progra m?
A.
This is when the progra m cannot find the defaul t opti o ns file, whi c h is kno w n to occur on
certai n versio ns of Li n u x. In the file chooser you are supposed to navi gate to where you have
installe d C A T C H and select the setup.i ni file. This is a kno w n bug that wi l l be addressed in
future versio n of C A T C H but does not occur very often.
Q.
Can I use the progra m when C A T C H is calculati n g?
A.
Yes you can. W h e n you have initiated a very big task, you can sim p l y put the progress
wi n d o w aside and conti n ue using the progra m. Y o u can even start more tasks, but keep in
min d that perfor m a n c e wi l l decrease when you have mul ti p l e tasks runni n g at once. This is
especial l y true if your com p u te r is not equi p pe d wit h a mult i- core processor.
Q.
W h y am I able to load any sort of file I want?
A.
Current l y we have not yet perfected our file filter. Right no w it is the responsi b i l i t y of the user
to make sure that onl y vali d files are selected for use with i n C A T C H . Also, file errors are
min i m a l so if results are very unexpe cte d or the progra m crashes, veri f y that the files you use
are vali d *.wig, *.pwi g or *.catch files, depend i n g on where you atte m p t to load these files.
Q.
I own a M ac and don’t have a right- mouse butto n, what do I do?
A.
Bu y a decent mouse. Seri ousl y, all progra m s these days requi re a right mouse button to
functi o n. W h y Ap p l e does still suppl y one-butto n mice is beyon d us but we do not support
them in C A T C H .
Q.
W h y am I not able to see the relati ve align m e n t of the tracks?
A.
W e are wor k i n g on this and it wi l l be added in future versi o n of C A T C H .
Q.
The C A T C H algori t h m is slo w. Can’t you make it faster?
A.
Yes we can, and we are in fact alread y wor k i n g a versio n of C A T C H that wi l l wor k wit h
parallel processi n g. This means that by using a still secret and m ysteri o us process we wi l l
eventual l y be able to increase the speed by a factor of 40 or more. Stay tuned for this.
