.SH DESCRIPTION |
| 46 |
|
A complete XML description is written to the standard output, |
| 47 |
|
which is normally redirected to a file. |
| 48 |
|
.PP |
| 49 |
+ |
The |
| 50 |
+ |
.I \-p |
| 51 |
+ |
option by itself turns off the progress bar, whose length may be set |
| 52 |
+ |
by an immediately following integer argument. |
| 53 |
+ |
(The default progress bar length is 79 characters.)\0 |
| 54 |
+ |
.PP |
| 55 |
|
The maximum resolution of the tensor tree may be controlled by the |
| 56 |
|
.I \-g |
| 57 |
|
option, which defaults to a value of 6. |
| 76 |
|
the four components, and if the first component |
| 77 |
|
is isotropic, all components must be isotropic. |
| 78 |
|
A similar rule holds for anisotropic inputs. |
| 79 |
+ |
The |
| 80 |
+ |
.I \-l |
| 81 |
+ |
option may be used to specify the maximum number of lobes in any |
| 82 |
+ |
interpolated radial basis function. |
| 83 |
+ |
The default value is 15000, which generally keeps the interpolation tractable. |
| 84 |
+ |
Setting the value to 0 turns off this limit. |
| 85 |
