Hi everyone,

I have approximately 100 rows (samples) and 4000 columns (Trait1, 2, ... n) that look like below.

Input
Size0.10.30.50.60.911.12.2
SampleTrait1Trait2Trait3Trait4Trait5Trait6Trait7Trait8
A00011000
B11101111
C00111000
D00000011

<tbody>
</tbody>

For each sample, I want to scan the block of numbers, and report the size of the block (first row). For example, Sample A has first block of 0s of size 0.5 (0.5 - 0.0); second block of 1s of size 0.3 (0.9 - 0.6); and third block of 0s of size 1.2 (2.2 - 1.0).

Desired output
SampleBlock1Size1Block2Size2Block3Size3
A00.510.301.2
B10.50011.3
C00.310.401.2
D0111.1

<tbody>
</tbody>

Please note that for sample B, which as only 1 zero, the size is also zero as it is not a block. Therefore, if there's a value by itself (count of 1), then the size should be zero.

I hope someone here can help me with this as my data size is pretty big and it is killing me to scan it by color-coding the spreadsheet.

Thank you for your generous help, as always.

Why is it not 0.4 (0.5 - 0.1)?

Counting for this data begins with 0 so the first 'size' is value - 0.

Actually, in hindsight, I should have listed 0 as the first value in the 'Size' row to avoid confusion.
