|          |             | (switched to      |
|          |             | `gitbook <http:// |
|          |             | gitbook.com/>`__  |

| 1.5      | 2011-10-28  | ReadSegy.m :      |
|          |             | Added option      |
|          |             | 'traces' that     |
|          |             | allow fast        |
|          |             | reading of        |
|          |             | specific traces.  |
|          |             | When the 'minmax' |
|          |             | option is used,   |
|          |             | the corresponding |
|          |             | traces are first  |
|          |             | located through   |
|          |             | header files, and |
|          |             | then data are     |
|          |             | read using the    |
|          |             | 'traces' options. |
|          |             | For larger files  |
|          |             | this cause the    |
|          |             | reading time to   |
|          |             | decrease          |
|          |             | significantly     |
|          |             | when using the    |
|          |             | 'minmax' option.  |

|          |             | 'SkipData'        |
|          |             | conflict with     |
|          |             | Robust Control    |
|          |             | Toolbox. Disabled |

|          |             | specification of  |
|          |             | line color. Allow |
|          |             | overlaying wiggle |
|          |             | plots. Allow NaN  |
|          |             | value in 'VA'     |
|          |             | style plotting.   |

|          |             | 'ReadSegyTraceHea |
|          |             | derValue'         |
|          |             | and               |
|          |             | 'WriteSegyTraceHe |
|          |             | aderValue'        |
|          |             | that can be used  |
|          |             | to read and write |
|          |             | the               |
|          |             | TraceHeaderValues |
|          |             | one by one. Much  |
|          |             | faster than       |
|          |             | reading the whole |
|          |             | dataset.          |

|          |             | partial segyfile  |
|          |             | (using time and   |
|          |             | header ranges)    |
|          |             | from GUI (ctrl    |
|          |             | X). Enabled       |

|          |             | operations        |
|          |             | causing a         |
