How to return parts of a string with regular expression : <p>I have multiple strings in the format:</p>

<pre><code>"s mus_musculus.1          3003214       6673 +  195471971 ctctcctatggcggggaaggtgcctggatgtctaaagc-----------------ctgaa-atggggatctatcccagaagctgtgtagcttctgcctgtcccagaagctgtgttgtttct"
</code></pre>

<p>How can I use regular expressions to pull out the first number sequence (ie 3003214), and then the final sequence of "c, t, a, g, and -"? </p>

<p>I have tried various regular expression builders but have not been able to figure it out. </p>

<p>Any help would be greatly appreciated! </p>
